1957 So You Say Its Birthday! Butch Vig, drummer with American rock band Garbage, producer extraordinaire (Sonic Youth, Smashing Pumpkins, Green Day, Foo Fighters, as well as that album by those three guys from Seattle? What was it called?)
1968 ‘Hello I Love You’, by The Doors starts a two week run at .1 on the US singles chart. Some controversy has surrounded the song as Ray Davies of the Kinks has asserted that the main structure of the song was plagiarized from the Kinks song “All Day and All of the Night“. According to Davies, an out of court settlement was reached between the bands over the riff. The song was also one of the first stereo 45rpm records.
1975 ‘One of These Nights‘ by The Eagles goes to #1 on the US singles chart. The song, the title track of the album by the same name, was written by Don Henley and Glen Frey, and was a conscious attempt by the Eagles to get away from the country-rock/ballads that they were known for up to that point. It was influenced by R&B music and disco, and was about putting things off til another day instead of dealing with it at that moment.
