Following the release of "Eldorado", Kelly Groucutt was recruited as bassist and in early 1975, Melvyn Gale replaced Edwards on cello. The line-up stabilised as the band took to a decidedly more accessible sound. ELO had become successful in the US at this point and the group was a star attraction on the stadium and arena circuit, and regularly appeared on "The Midnight Special" more than any other band in that show's history with four appearances (in 1973, 1975, 1976 and 1977).
