Yes, for every band like The Beatles, there is the sorry existence of Mrs Brown’s Boys. Then there was John Lennon holding a soda aloft, putting the straw up his nose, and joking that he had been caught sniffing coke. The band, and perhaps more importantly, Brian Epstein, did not discriminate against anything that there was a market for. And there was most certainly a market for camp comedy in the 1960s. Perhaps the most bizarre factor of all is not the man behind the monumental hit, but the song itself.
