There are 3 bands that share the name Mammoth and one band formerly known as Mammoth: (UK) 1. After the split of Gillan in 1982, the bearded John McCoy (bass guitar; 19 stone) recruited session musicians 'Tubby' Vinnie Reed (drums; 22 stone), 'Big' Mac Baker (guitars; 24 stone) and Nicky Moore (vocals; 20 stone and 5'6") for his solo project.
Initially christened 'Dinosaur', they changed their names after complaints from a similarly titled California blues outfit.
