Oh, man. I cannot believe this got past me … but it did.

On April 10, 1970 — that’s 50 years ago, folks — Paul McCartney announced casually in an interview that The Beatles had broken up. The music ended. The greatest rock ‘n roll band in history was no more.

That’s how it came about. Paul McCartney told us.

I have said before that the group founded by John Lennon, who then asked Paul McCartney to join him, who then brought along George Harrison to play with the two of them and then hired Ringo Starr to replace the drummer that none of them liked … they helped raise me.

I saw their performance on the “Ed Sullivan Show” in 1964. I followed them closely. I came of age about that time. Their music would end up fueling the my musical taste right on through to the present day.

They recorded so many great songs. They wrote such wonderful music. They, indeed, helped a generation of young people come of age. They helped raise us all.

Of all the music I have heard over the years, one song stands out. It is the only song I remember where I was when I heard it for the first time. It was the second half of a song I heard initially in September 1968. I turned on a transistor radio in a U.S. Army barracks in Fort Lewis, Wash. I listened to the end of a song that went on seemingly forever. It was “Hey Jude.”

I fell in love with that melody. On the spot. Right then and there.

It became a sort of anthem for me. I cannot hear it enough.

Less than two years after hearing what I consider to be the greatest song ever recorded, they would call it quits. They went their separate ways.

It was — gulp! — 50 years ago. Wow! I still miss those guys.

I am acutely aware that today would have been John Lennon’s birthday. He would have turned 79. He didn’t make it nearly that far into his life.

A gunman ended it all for John in December 1980. He died at 40.

I want to take the opportunity today while marking John Lennon’s birthday to take stock of what might have transpired had this genius been allowed to live. We, of course, cannot know with any certainty.

I’ll let my heart speak for a brief moment.

My ticker tells me John Lennon would have continued to make memorable music. He would have written lyrics that stand the test of time. He would have built on his already priceless body of work, most of it of course in tandem with his songwriting partner, Sir Paul McCartney. Might they have reconciled enough to re-form their partnership? Oh, one only can hope they might.

Hey, it’s also quite possible that John Lennon would have been knighted just as Sir Paul and Sir Richard Starkey — aka Ringo Starr — have been honored by their queen. I only can imagine the statement a Sir John Lennon would have issued upon getting this honor from the crown. I’ll add as well that George Harrison, who died in 2001, deserved to be knighted. Alas, it won’t happen.

John Lennon was my favorite Beatle. It might be only because we shared the same name. In reality, I was drawn by his quirkiness, his snarky approach to celebrity and his biting wit.

The boy could sing, too.

All of this is my way of wishing fate had dealt John Lennon a better hand than what he was forced to play.

I will miss this genius forever. Happy birthday, John.

ALLEN, Texas — So, I walked into a sporting goods store today with my sis and her husband. We made a purchase and walked to the checkout counter.

The young man took one look at my Beatles shirt and said, “Hey, I love your shirt. I am named after one of those guys.”

I looked at his name tag with the name: Lennon.

What in the world? Yes, his dad is a major Beatles fan. So is the young man, who I figure might be 20 years of age.

“Do you know how John Lennon died?” I asked. “Oh yes. I’ve been told all about it. I have read all about it.”

My sis told the young man how we — she and I — attended a Beatles concert in Portland, Ore., in August 1965. “Front-row center seats,” she told him. Lennon wanted to know how we liked it “with all the screaming.” It was a challenge to hear anything, I mentioned.

Sis told him George was her favorite Beatle.

Lennon said his mom wanted to name his brother after Paul McCartney. I wondered: Huh? Well, I suppose he could be called “Mac.” Lennon’s parents ended up naming his sibling something else.

And so . . . I received yet another example of how the music of my generation lives forever. The Beatles’ legacy will live on for as long as human beings are able to listen to music.

I know he’s not the only child — or grandchild — of those who grew up listening to those fellows.

As I reminded young Lennon, “These guys (pointing to the image on my shirt) helped raise me.”
