Slade - cum on feel the noize, 1973

"I was at a Chuck Berry gig in '72 and everybody was singing his tunes. He kept stopping and letting the crowd sing and it wasn't just a few people, it was everyone. I thought it was amazing and thought – why not write the crowd into the songs, and so we got round to 'Mama Weer All Crazee Now' and 'Cum On Feel the Noize' and all the chants were written into the tunes."
