ELO became less popular during the 1980s. They had fewer hits. They recorded the "Xanadu" soundtrack with singer Olivia Newton-John. They also released the albums "Time" (with the title song and "Hold On Tight" as singles) in 1981, "Secret Messages" (with "Stranger") in 1983, and finally "Balance of Power", which included "Calling America", in 1986. By this time the classical musicians had left. Lynne now was recording their parts with synthesizers or session players.
