While playing with Barefoot in
Birmingham, he was spotted by ELO's
Jeff Lynne; and after Lynne,
Bev Bevan and
Richard Tandy had watched him play, he was invited to join ELO, to replace
Mike de Albuquerque, who had recently left the band. Upon joining, he was asked to adopt a stage name because ELO had already had several members named Michael, Mike or Mik; he chose Kelly (a school nickname). The first Electric Light Orchestra album to feature Groucutt on bass guitar and as a backing vocalist was
Face the Music (1975). He assumed lead vocal duties on one or two album tracks typically, and his vocals can be heard on later ELO songs, most prominently on songs such as "
Nightrider" (1975), "Poker" (1975), "Down Home Town" (1975), "Above the Clouds" (1976), "Across the Border" (1977), "Night in the City" (1977), "Sweet is the Night" (1977) and "
The Diary of Horace Wimp" (1979). Groucutt often displayed his operatic vocal talents during live performances of "
Rockaria!" (1976), though these were not performed in the studio. Groucutt continued contributing on the albums
A New World Record (1976),
Out of the Blue (1977),
Discovery (1979),
Xanadu (1980),
Time (1981), and the early sessions for
Secret Messages (1983). By
Time, Groucutt's role in the band was reduced by Lynne from co-lead vocals to backing vocals exclusively. In 1982, he released his self-titled, debut
solo album,
Kelly. This album featured fellow ELO members
Bev Bevan,
Richard Tandy,
Mik Kaminski and their orchestral co-arranger and conductor
Louis Clark. In 2001, the album was remastered for CD. Groucutt remained with ELO until the onset of the recording sessions for the album
Secret Messages in 1982. It was at this juncture that he left the band, unhappy with royalty payments during his tenure, and made the decision to sue management and band leader
Jeff Lynne. A settlement for the sum of £300,000 () was reached out of court prior to proceedings, He is credited with playing bass on
Secret Messages, although the 2018 album liner notes state that he only played on four songs ("Train of Gold" and "
Rock 'n' Roll Is King" from the single disc release and "No Way Out" and "
Beatles Forever" from the original double album). During the mid-to-late 1980s, Groucutt worked further on his solo career, including the
We Love Animals EP in 1985 to benefit the RSPCA. One of his songs from the EP, "The Fox", was later reworked for the
ELO Part II album
Moment of Truth. Groucutt played a
Gibson G3 bass as well as a
Fender Precision Bass, an Ovation acoustic guitar and
Hofner 500/1 bass guitar during much of his tenure in Electric Light Orchestra. == OrKestra ==
