Context paragraphs:
The Six Teens (song): "The Six Teens" (often spelled as "The Sixteens") is a 1974 song by British glam rock band Sweet, written by Nicky Chinn and Mike Chapman, appearing on Sweet's album "Desolation Boulevard".  The song was Sweet's first single simply as "Sweet" (previously, the band was known as "The" Sweet).

The Sweet (album): The Sweet was a compilation album released as Sweet's debut album in the USA and Canada, substituting for the 1971 UK album ""Funny How Sweet Co-Co Can Be"".  (The band's second album, ""Sweet Fanny Adams"" was also not given a US release, but tracks from that and the band's third album ""Desolation Boulevard"" were combined on the US version of that album to compensate for this.)

The Ballroom Blitz: "The Ballroom Blitz" (often called ""Ballroom Blitz"") is a song by the British rock band The Sweet, written and produced by Nicky Chinn and Mike Chapman.

Ain't No Woman (Like the One I've Got): "Ain't No Woman (Like the One I've Got)" is a 1973 hit single written by Dennis Lambert and Brian Potter, released as a single by the Four Tops on the ABC/Dunhill record label, from the album "Keeper of the Castle".  It reached number four on the U.S. "Billboard Hot 100," number one on the "Cash Box" Top 100, and became a Gold record.

Desolation Boulevard: Desolation Boulevard is the third album by Sweet originally released in the United Kingdom in November 1974.  Two different versions of the album were released.  One by RCA Records in Europe, and another by Capitol Records in the United States, Canada and Japan.  The RCA version contains the single "Turn It Down" and the original recording of "Fox on the Run".  The Capitol version, released in the United States in July 1975, includes the 1973 hit single "The Ballroom Blitz" and the single version of "Fox on the Run".

If You Want Me to Stay: "If You Want Me to Stay" is a 1973 hit single by Sly and the Family Stone, from their album "Fresh".  The single was the band's final Top 20 pop hit, and is the best-known of its post-"There's a Riot Goin' On" recordings.

Miss O'Dell: "Miss O'Dell" is a song by English musician George Harrison, released as the B-side of his 1973 hit single "Give Me Love (Give Me Peace on Earth)".  Like Leon Russell's "Pisces Apple Lady", it was inspired by Chris O'Dell, a former Apple employee, and variously assistant and facilitator to musical acts such as the Beatles, Derek & the Dominos, the Rolling Stones, Bob Dylan and Santana.  Harrison wrote the song in Los Angeles in April 1971 while waiting for O'Dell to pay him a visit at his rented home.  As well as reflecting her failure to keep the appointment, the lyrics provide a light-hearted insight into the Los Angeles music scene and comment on the growing crisis in East Pakistan that led Harrison to stage the Concert for Bangladesh in August that year.

Magic (Gillan album): Magic is an album by British rock band Gillan, their final collaboration, released in October 1982.  It features eight original songs, mostly co-written by Ian Gillan and Colin Towns, and a cover of Stevie Wonder's 1973 hit single "Living For The City".  This cover was released as a 7" single, in both picture-bag and picture-disc editions, and was accompanied by a promotional video.

I'm Just a Singer (In a Rock and Roll Band): "I'm Just a Singer (In a Rock and Roll Band)" is a 1973 hit single by the English progressive rock band The Moody Blues.  It was first released in 1972 as the final track on the album "Seventh Sojourn".  "I'm Just a Singer (In a Rock and Roll Band)" was later released as a single in 1973, with "For My Lady" on the B-side.  It was the second single released from "Seventh Sojourn", with the first being "Isn't Life Strange" (also written by John Lodge).

Friends (Bette Midler song): "Friends" (also titled "(You Got to Have) Friends") is a 1973 hit single by Bette Midler.  It was written by Buzzy Linhart and Mark "Moogy" Klingman.  In the United States, the song reached #9 on the Adult Contemporary chart and reached #40 on the "Billboard" Hot 100 chart.
