1955: Bill Haley's "Rock Around The Clock" reaches #1 in the UK and is considered to be the first Rock and Roll record to accomplish that feat.
1967: "Incense and Peppermints" by The Strawberry Alarm Clock hits the top of the Billboard Pop chart. The recording was initially intended as a 'b-side' and the lead vocal is actually that of a friend of the band, 16 year old Greg Munford, who was just hanging around during the session. Munford was not even a regular band member, but ended up singing a tune that would become a Rock and Roll standard and sell over a million copies. Despite this success, Munford never actually joined the original group and drummer Randy Seol sang the song in concert. Although it was a huge success in America, the single didn't chart at all in the UK.
1973: After cracking Billboard's Top Ten with "It Don't Come Easy" (#4) and "Back Off Boogaloo" (#9), Ringo Starr reaches number one with "Photograph", a song he co-wrote with George Harrison.
1976: Queen's, "Bohemian Rhapsody" hit number one in the UK, where it stayed until the end of January 1977, longer than any other song since Slim Whitman's "Rose Marie" in 1955. The promotional video that accompanied the song is generally acknowledged as being the first UK Pop video and cost 5,000 Pounds to produce.
1975: Less than three months after achieving their first number one record, "Get Down Tonight", KC And The Sunshine Band return to the top of the Hot 100 with "That's The Way (I Like It)". It made #4 in the UK.
