Back in the Bad Old Days when I was a member of a Cheilidh band we used to feature a sort of 'Duelling Spoons' with two members of the band doing afeatured spoons 'solo' which culminated inthem coming back to the band playing the spoons around each other ! Excellent Showmanship , and always well received !!
No reason why two decent bodhran players shouldnt do a similar thing !!
