Stick an Edith Piaf cd on to play before kick off to make them feel at home. For the benefit of the younger readers on here she was a French singer back in the 50/60s
The first two lines of the Volare tune work well enough on their own and could be popular with the fans.
Sorry when I see his name I just picture Jim Tavare. Remember him? Comic with a cello. 'Jim Tavare, in cabaret'
We've got Cavare, Dimitri Cavere, I Just Don't Think You Understand! He's Got a French Mam, A **** Like a Battering Ram, We've got Dimitri Cavare!
