The older brother of bassist Norman Watt-Roy, guitarist/singer Garth Watt-Roy was born in Bombay, India, in 1947. The family moved to England just as rock & roll was taking root on the Sceptered Isle. From 1955 on, the older Watt-Roy sibling grew up in Highbury, North London, and later in Essex, and by his mid-teens had become a very capable rhythm guitarist and backup singer. He could probably have emulated any sound coming across the Atlantic (or out of the skiffle boom at home), but what he and his brother liked best were the soul sounds of Stax/Volt Records. He and his younger brother played in local bands and, in 1967, formed the Living Daylights, a psychedelic pop band, with lead guitarist Curt Criswell and drummer Roy Heather. The Living Daylights got to record a small handful of single sides for Philips Records before breaking up, and the Watt-Roy brothers next formed a nine-piece soul band called the Greatest Show on Earth. During the early '70s they passed through the lineup of Glencoe, and Garth Watt-Roy went on to work with the lineups of such diverse bands as Steamhammer, East of Eden, and the Marmalade. During the mid-'70s, he became part of Bonnie Tyler's backing band, on record and on-stage, and he later joined the pop-soul band the Q-Tips. He has been relatively inactive as a guitarist in the recording field since the mid-'80s, but he was involved in several studio projects in other capacities in the 1990s.
