Fair comment Doug, but how short would a song have to be before it would stop us singing it?

Louie, Louie (cannot spell it) is a great rock song but not an acoustic contender.

And for all those who seem to imply that lots of Beatles songs will work, go and do what I have done, go and read the lyrics of them all. Many are not poetry:

Come on come on come on is such a joy come on is such a joy
Come on take it easy, come on take it easy, take it easy take it easy
Everybody has got something to hide except me and my monkey

The deeper you go the higher you fly
The higher you fly the deeper you go
So come on come on

Your inside is out your outside is in
Your outside is in your inside is out
So come on come on

Even when they are deep and meaningful they are often short.
