[2] Tandy was born on 26 March 1948 in Birmingham, Warwickshire and educated at Moseley School, where he first met future bandmate Bev Bevan.

[4] Tandy joined Electric Light Orchestra (ELO) in 1971, replacing previous bass guitarist Rick Price.
In 1972, Tandy served as the bassist in the first live line-up of ELO, before becoming the band's full-time keyboardist after the departure of Bill Hunt who left with Roy Wood to form Wizzard.
