1976: John Sebastian, who had left The Lovin' Spoonful for a solo career in 1968, hit the top of Billboard Magazine's Hot 100 chart with the theme to the TV show, Welcome Back Kotter. John would later say that he wrote the song in 15 minutes. Oddly enough, it even reached #93 on the Billboard Country Chart.
1983: After cracking the Top 20 a year earlier with "The Break-up Song", San Francisco's Greg Kihn Band reaches #2 on the Hot 100 with a song called "Jeopardy". A year later, Weird Al Yankovic will parody the song as "I Lost On Jeopardy", which has since been referenced several times on the game show itself.
1965: James Brown reworks a song called "I Found You" by Yvonne Fair and comes up with "I Got You" (I Feel Good). It will become the biggest hit of his career, reaching #3 in the US and #29 in the UK.
1969: Creedence Clearwater Revival's "Bad Moon Rising" is released. It will reach #2 in the US and top the chart in the UK.
1970: Four students were shot and killed by the National Guard at Kent State University in Ohio during an anti-war demonstration. Neil Young reacted to the senseless slayings by writing and recording the song, "Ohio", with Crosby, Stills & Nash, the very next day.
