Oh, what a night
Late December, back in '63
What a very special time for me
As I remember, what a night

More music...

When I get older, losing my hair

Many years from now

Will you still be sending me a valentine

Birthday greetings, bottle of wine?

If I'd been out till quarter to three

Would you lock the door?

Will you still need me, will you still feed me

When I'm sixty-four?

Trivia - - who sings this one?

^ Hmm, well, I always thought it was Paul.

Just like "La, a note to follow Sol", here is 65, a number to follow 64!

"Get your kicks on Route 66"
