Jethro is the stage name of British stand-up comedian Geoffrey Rowe, based at Lewdown in Devon. Rowe was born in 1948 in St Buryan, a village in west Cornwall.
After leaving school, Jethro was apprenticed as a carpenter and then worked as a timber man in a tin mine. However, aged eighteen he joined the St. Just and District Operatic Society and, in addition to his bass voice, locals found he had a talent to make an audience laugh. He began visiting the pubs of Cornwall to sing and joke and was quickly hailed as Cornwall's top comic.
