Miguel, John Grant and country star Hunter Hayes have recorded cover tracks from Elton John's classic album Goodbye Yellow Brick Road for a new 40th anniversary tribute album. Promoting his upcoming release, The Diving Board, during a concert at the University of Southern California on Monday (16Sep13), the Rocket Man told students that Hayes had covered the title track. He said, "He played all the instruments and he blew my mind." During his set at USC, Elton performed with the USC Thornton School of Music Orchestra conducted by film composer James Newton Howard and he also played five songs from The Diving Board with a student choir and brass ensemble. Tracks performed included Philadelphia Freedom, Tiny Dancer, Levon, Your Song, Bennie and the Jets, Goodbye Yellow Brick Road, I Guess That's Why They Call it the Blues and Rocket Man.
