Paul McCartney, the former Beatle whose new album, “Memory Almost Full” was recently released on a wave of good reviews, told “Good Morning America” last week that he regrets having written the song “When I’m 64.”

The song was on The Beatles’ album “Sgt. Pepper’s Lonely Hearts Club Band,” released 40 years ago this month.

McCartney will turn 65 years old on Monday. He said the song draws undo attention to age.

“… It’s actually not been bad, you know, really. People still feed me and one or two people still need me,” he said.

It sounds kinda sad considering he’s going through a nasty divorce with Heather Mills. On top of everything else, this week marks their fifth wedding anniversary.

I’ve been a Paul McCartney fan for more than 30 years. The first single I ever bought was “Band On The Run” from 1973. I was 10 then. Paul was 31. I’ve seen Paul regret quite a few things publicly over the years: his LSD use and claim in the 60s that it was OK; his tossing a bunch of pot in his suitcase that was found in Japan that landed him in jail; his ramming a reporter’s car with his jeep after John Lennon’s death; his “people” lying to reporters about where his wife Linda died in an attempt to preserve the family’s privacy at his ranch in Arizona.

When it came to The Beatles, I was more of a John Lennon fan, but I faithfully bought all of their solo albums after the breakup, even Ringo’s. I always kind of felt sorry for Paul. He really had more to prove than the rest in some ways because as Beatles John was always considered the thinker, or philosopher of the group. George was the mystic and Ringo the clown. Paul, cursed with good looks, was unfairly referred to as the pretty Beatle. It seemed some people couldn’t see past that enough to really appreciate his musical brilliance.

And, it seemed with every solo album release by Paul McCartney, someone would say: “He’s really mellowed out now.” As if he’d spoiled, you know, turned rotten and molded and imploded.

Think about it. When have you known Paul McCartney NOT to be “mellow” for the most part? Even if Paul or John wrote a whole song, they had a standing agreement when they were Beatles that it would be credited a Lennon-McCartney composition. But, the one who sang lead is the one who primarily wrote that song. Of course George Harrison wrote his own stuff and they usually let him slip a song on each album.

After the breakup George got his revenge as the first ex-Beatle to have a No. 1 album with “All Things Must Pass,” a triple album that included stuff that didn’t get on Beatle projects.

Paul is the Beatle who did “And I Love Her,” “Michelle,” “Let It Be,” “All My Loving,” “Mother Nature’s Son,” “Golden Slumbers,” “Rocky Raccoon,” “I Will,” “She’s Leaving Home,” “For No One,” “Eleanor Rigby,” “Blackbird” and of course, “Yesterday,” probably the most mellow Beatle song ever (which he recorded 42 years ago this week).

He was the mellowest Beatle of all. It’s actually more surprising when you realize the harder rock jewels that were his during the Beatle years like “Helter Skelter” and “Back In The USSR,” and the mellow-turned-screaming Paul on the longest standing No. 1 single The Beatles ever had — “Hey Jude.”

The new album doesn’t sound like Paul’s “mellowed out.” At times it almost sounds like he may be trying too hard not to. If a tour comes, don’t pass up a chance to see him. I’ve seen him twice — once around 1990 when everyone flicked their bics and held them high as he sang “Yesterday,” solo, with his acoustic in the spotlight, and once about four years ago when everyone flipped open their cell phones and held them up when he sang “Yesterday,” solo, with his acoustic in the spotlight.

The first time I saw him he paid tribute to John during his concert. The next time he paid tribute to John and George. But when he hits the stage there’s nothing mellow about his shows — always filled with high octane classics from his solo career, his years with Wings and mostly The Beatles.
