The Electric Light Orchestra Part II was a British-American rock band formed by Electric Light Orchestra drummer and co-founder Bev Bevan. The band also included former ELO bassist and vocalist Kelly Groucutt, and violinist Mik Kaminski for most of its career, along with conductor Louis Clark, who toured as a guest with ELO in its later years; ELO cellist Hugh McDowell likewise briefly performed with the group in 1991. Alongside these ELO personnel, Part II rotated through several ELO-unaffiliated frontmen during its lifetime, with singer-songwriter and keyboardist Eric Troyer the only one to retain constant membership.
After Bevan left the band in late 1999, he sold his half of the rights to the Electric Light Orchestra name back to Jeff Lynne, and the band changed its name to The Orchestra.
