[8] The first Electric Light Orchestra album to feature Groucutt on bass guitar and as a backing vocalist was Face the Music (1975).

[9] 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).

This album featured fellow ELO members Bev Bevan, Richard Tandy, Mik Kaminski and their orchestral co-arranger and conductor Louis Clark.

[13] A settlement for the sum of £300,000 (equivalent to £1,278,600 in 2023[14]) was reached out of court prior to proceedings,[13] but Groucutt later reflected that he regretted suing Lynne.

Groucutt and Kaminski eventually became dissatisfied with the poor promotion and record label the band received, especially as their first album, Beyond The Dream was delayed.

Groucutt would alternate lead vocal duties with Troyer and newly-hired guitarist Phil Bates for much of the group's remaining lifespan.

When the group released Moment of Truth, Groucutt contributed the song "The Fox", and co-wrote "Blue Violin" and "Twist of the Knife".

When Bev Bevan sold his half of the rights to ELO back to Jeff Lynne in 1999, Groucutt chose to remain with the group, which was renamed The Orchestra.

He again made writing contributions to the group's next album, No Rewind, by co-writing the closing track, "Before We Go", on which he also sang lead vocals.
