I’ve been bracing myself for the idea of Paul Simon, who is 76,  playing his last shows this summer. He will make a career finale in Forest Hills on September 22nd after two nights at Madison Square Garden. It seems much too soon.

At the same time, another Paul is just gearing up for another arena tour. Paul McCartney, also 76, just announced four dates in Canada. They are quite literally at the same time as Simon’s farewell shows, although McCartney does have September 21-27 off on his current schedule. He could show up in Forest Hills.

With McCartney, anything is possible. The Canada dates kick off the “Freshen Up” tour for his new album, “Egypt Station,” due September 7th. And even though McCartney just played several dates in the New York area last September, you know he will fill up MSG, Barclays in Brooklyn, Prudential Center in Newark once again without any difficulty.

For McCartney to slide into MSG, his bookers will have to deal with not only Simon, but the monthly Billy Joel (only 69) and several Elton John dates. Elton, 71, is on his own farewell tour that goes on well into the year 2020.

Will McCartney ever retire? I don’t think so. He has some kind of cosmic challenge going on with Mick Jagger (turning 75 this month), who’s also touring this summer with the Rolling Stones. And Ringo Starr (turns 78 this week) is out there with his band. Beatles vs. The Stones. It’s the Yankees and the Red Sox. It will just go on and on.

Big news from the Beatles:

They’re going to release a first ever sing-a-long version of the movie “Yellow Submarine” next month to support the 50 th anniversary.

The group is already releasing the movie in various locations beginning July 9th. I saw a new print of it a couple of weeks ago and Sgt. Pepper’s Lonely Hearts Club Band has never looked better, just like Pepperland and the Blue Meanies. The Nowhere Man is still nowhere.

Directed by George Dunning, and written by Lee Minoff, Al Brodax, Jack Mendelsohn and Erich Segal, Yellow Submarine began its voyage to the screen when Brodax, who had previously produced nearly 40 episodes of ABC’s animated Beatles TV series, approached The Beatles’ manager Brian Epstein with a unique vision for a full-length animated feature.

Check thebeatles.com for more info on tickets to both versions.

This isn’t the only 50 th anniversary for the Beatles this summer. From July 31st to August 2nd, 1968 they recorded “Hey Jude.” The single was released at the end of August and spent 7 weeks at number 1. The flip side was “Revolution,” which also went to number 1. The song were original, they weren’t sampled from something released 30 years earlier. They have remained classics, the best of the group’s amazing canon.

There will also be a 50th anniversary edition of “The White Album” in November, with outtakes and all sorts of extras.

EXCLUSIVE What have you been doing this year? Tony Bennett, who turns 92 in August, has been pretty busy from what I hear. He’s going to save Columbia Records from their year long dry spell.

Back in October 2014, Tony told me he and Lady Gaga already had a planned sequel to their “Cheek to Cheek” hit album. He said it would be all Cole Porter and he wasn’t kidding. On this past May 28th, fans saw Bennett and Gaga go in and out of Electric Lady Land Studios on West 8th St. I can tell you they were putting the finishing touches on that same Cole Porter album. 

My sources say we’ll hear the second Bennett-Gaga album in 2019, because both artists have other projects that will come first.

Gaga, of course, will hit us with “A Star is Born” in September. She not only stars in it but has a whole album of songs to accompany the movie.

Tony, I’m told, will announce another duets album on his birthday. A Diana Krall duets album of songs by the Gershwins will hit stores in September, right before the Grammy deadline cut off on September 30th. Tony and Diana have sung together on off tracks in the past, but this is a whole concept album, and it’s on Columbia. We need new Tony Bennett albums now more than ever!

So that’s what Tony’s been up to, that and doing concerts all over the world, even at almost 92!

Ed Sheeran is being sued again for his hit, “Thinking out Loud.” Last year, co-writer of Marvin Gaye’s Let’s Get it On sued Sheeran. Now it’s a music firm that owns part of the copyright, Structured Assets. They want $100 million. Gaye’s heirs, who won a $5 million case against Robin Thicke for “Blurred Lines,” haven’t filed yet. But they will.

Sheeran loves to nick pieces of other songs for his hits. His big hit, “Perfect,” sounds so much like the Righteous Brothers’ “Unchained Melody,” that YouTubers have mixed videos for it. Alex North and Hy Zaret wrote the song in 1955, and it was covered by several artists. But the Righteous Brothers had the biggest hit in the 60s. Their version was rediscovered for the movie “Ghost” in 1989.

Hy Zaret, who wrote the lyrics, died in 2007 but presumably his estate has a lawyer. PS The song is called “Unchained Melody” because it was written for a movie called “Unchained.” Zaret never used that word, but the song became the melody from “Unchained.”

As for “Let’s Get it On,” poor Marvin Gaye. I used to hear “Thinking Out Loud” on the radio and say, “Damn, that sounds just like Let’s Get It On.” Just like Blurred Lines” sounds just like “Got to Give it Up.” Sheeran may have to sell one of his tattoos to pay for this mess.
