WHEN I’M 64

The Beatles band is now 64 years since they got together, so why did they spell their name with an A instead of and E?
Some just learned the reason their name is spelled with an A is because it's a music pun, like the word beat. Get it?
Why didn't we all know this? Did you know this? I had posters of The Beatles in my bedroom and I never realized this. https://m.youtube.com/watch?v=wUDRIC5RSX4&pp=ygUUd2hlbiBpJ20gNjQgYmVhdG…
