Stuart Cosgrove; Celtic racists chanted like monkeys and banged the jungle drums

Stuart Cosgrove’s 2002 book Hampden Babylon. Here is the passage from Cosgrove’s book (P128):

"Week after week, the young black winger [Mark Walters] was subjected to a barrage of racial abuse, as prejudice squads at Parkhead, Tynecastle and Fir Park threw bananas, chanted like monkeys and banged the jungle drums in a desperate bid to put the player off his stride."
