Thanks for the Elton John songs. These songs were his big comeback in the 80s. Before this people figured he was washed up after he came out as gay and then got tangled in some drug problems. But he put out these hit singles and showed that he could compete on MTV with all the pop newcomers.
Also, on "Blues", that's Stevie Wonder on harmonica. Later in the decade they would sing together on the Burt Bacharach song "That's What Friends are For". This song was recorded as a charity single to raise money for AIDS research.
