The band signed with major label A&M Records in 1992 and released most notably Troublegum in 1994 and Infernal Love in 1995.  Ewing's departure in early 1996 preceded the arrivals of his replacement Graham Hopkins and Martin McCarrick on cello and guitar.  Neil Cooper replaced Hopkins on drums in 2002.

It has since been covered by numerous artists, including The Strangeloves, Eric Clapton, Cliff Richard, Kim Carnes, George Thorogood and The Grateful Dead.
