Tequila Sunrise - Eagles. Glenn Frey came up with the title. He was up all night drinking tequila and the sun was rising when he finished the song. The line, "take another shot of courage" refers to how if you drink tequila, it will give you courage to talk to women (although maybe not coherently).
Ticket To Ride - The Beatles. This was the first Beatles song that was over 3 minutes long.
Walking In Memphis - Marc Cohn. This was the first single for Cohn, who was discovered by Carly Simon. He won the 1991 Grammy for Best New Artist. The song line "walking with my feet ten feet off of Beale" refers to Beale Street, an actual street in Memphis.
What's Up - Four Non Blondes. Originally titled, 'What's Going On', a line repeated many times throughout the chorus. By renaming it, they kept it from being confused with the 1971 Marvin Gaye classic. The group consisted of 4 women who really didn't have blond hair. They named the group Four Non Blondes because they wanted to be known for their music, not their looks.
Wonderful Tonight - Eric Clapton. About Patti Harrison, Clapton's love interest at the time. They were married from 1979-1988. Clapton wrote this in 1976 while waiting for Patti to get ready for a night out. They were going to a Buddy Holly tribute that Paul McCartney put together, and Clapton was in the familiar position of waiting while she tried on clothes. Patti insisted on trying out outfit after outfit and each time she came downstairs he would say "You look wonderful". Becoming tired of this he eventually picked up his guitar and wrote the song 'Wonderful Tonight'.
Yesterday - The Beatles. Paul McCartney's song 'Yesterday', which was recently voted the most popular song of the century by a BBC poll, had music written before the lyrics. Paul used the working words 'scrambled eggs' before coming up with 'yesterday' while composing this song.
