ROOM TO MOVE
(John Mayall)

It may seem peculiar, baby, how I think of you.
If you want me, darling, here's what you must do:
You gotta give* me, 'cause I can't give my best unless I got room to move.

If you want me, darling, take me how you can.
I'll be circulating, 'cause that's the way I am.
You gotta give* me, 'cause I can't give my best unless I got room to move.
