Les; yes - can't get the song out of my head now!
I think it's a case of a different 'chorus'after each verse. I remember
We could .....
We could skate down the Avenue, but there isn't any ice.
We could ride on the trolleycar but we haven't got the fare
So we'll walk down the Avenue, yes we'll walk down the Avenue, yes we'll walk down the Avenue till we're there.
