This is a really good song johnnydoxx, just a suggestion on verse 3, hope you don't mind. only small but it would work better if the second line lost the and
But Ronnie’s dead, Tom’s sick in bed, Charlie’s mind got slow.
as it clashes with the and in the 3rd line, only small I know but it makes those lines flow better.
Look forward to hearing this and a nice bit of writing

You don't stop laughing when you grow old; you grow old when you stop laughing.
