[5] From the mid-1960s to early 1970s, he did session work for a company called Avenue Recordings, singing lead and backing vocals (occasionally along with Mick Box on guitar and Paul Newton on bass).

Byron sang on ten Uriah Heep albums: Very 'eavy Very 'Umble, Salisbury, Look at Yourself, Demons and Wizards, The Magician's Birthday, Live, Sweet Freedom, Wonderworld, Return To Fantasy, and High and Mighty.

Byron also gained a reputation for hard drinking, which eventually led to him being sacked from Uriah Heep at the end of a Spanish tour in July 1976.

Bron explained that Byron and the other Uriah Heep members had been in disagreement for some time over fundamental issues of group policy, and that the differences had been finally brought to a head following the band's recent tour of Britain and Europe.

[4] During this period, Byron teamed up with former Colosseum / Humble Pie guitarist Clem Clempson and former Wings drummer Geoff Britton to form Rough Diamond.

The opening track, "Between Two Worlds", is dedicated to David Byron and Gary Thain, both members of Uriah Heep who died at a young age.
