Hi Vegas,
I have the following answers.
47: Elbow bones and the racketeers
56: Houston Wells and the marksmen
59: Harold Melvyn and the bluenotes
74: Billy J Kramer and the Dakotas
79: Lloyd Cole and the commotions
...just thinking out loud :-)
9: Born between 1989 and 1993
the general concensus seems to be the teenagers, but these quiz setters are 'crafty folk' why would they miss out 1988 and 1994 (19,13) could it be the answer lies with college age 14-18 any thoughts?
