Olivia Newton-John and ELO, Xanadu
The "Grease" star and the Electric Light Orchestra released Xanadu in 1980 under Jet/MCA Records. The movie, "Xanadu," was actually a box office disaster, but the soundtrack sold. Despite the sonic success, Newton-John hated how she looked on the album cover so much that she ordered the company to destroy them. If you happen to have one, you can sell it for $9,000.
