Mama's Boys were a 1980s hard rock/heavy metal group from County Fermanagh, Northern Ireland featuring the three McManus brothers Pat, a.k.a. 'The Professor", (guitar and occasionally fiddle), John (bass and vocals), Tommy (drums). Later in their career they became a four-piece adding Keith Murrell on vocals in 1987 and replacing him with Mike Wilson in 1989. By 1980 Mama’s Boys had a bootleg circulating and were touring extensively in Ireland. They recorded and self-financed their first album, a raw blast of rock power entitled ‘Plug It In’ in 1982.
