Tons of Sobs is the debut album by English blues rock band Free, released in the UK on 14 March 1969.
 While the album failed to chart in the UK, it did reach #197 in the US.
 Free are cited as one of the definitive bands of the British blues boom of the late 1960s even though this is the only album of their canon that can strictly be called blues rock.
 The title of the album does not relate directly to the content of the album; it is possibly oblique reference to the darker, more sombre moments of the record.

 Free's self-titled second album failed to chart, before the 1970 follow-up "Fire and Water" peaked at number 2 on the UK Albums Chart, supported by the popular single "All Right Now" which reached the same position on the UK Singles Chart.
 The single also reached the top ten in a number of other regions, including the United States where it peaked at number 4 on the "Billboard" Hot 100.
A signature song is the one song (or, in some cases, one of a few songs) that a popular and well-established recording artist or band is most closely identified with or best known for, even if they have had success with a variety of other songs.
 There have also been instances where a film actor has acquired a signature song by giving a popular vocal performance in a feature.
 Signature songs can be the result of spontaneous public identification, or a marketing tool developed by the music industry to promote artists, sell their recordings, and develop a fan base.
The Loved Ones were an Australian rock band formed in 1965 in Melbourne following the British Invasion.
 The line-up of Gavin Anderson on drums, Ian Clyne on organ and piano, Gerry Humphrys on vocals and harmonica, Rob Lovett on guitar, and Kim Lynch on bass guitar recorded their early hits.
 Their signature song, "The Loved One" reached number two on Australian singles charts, and was later covered by INXS.
 In 2001 it was selected as number six on the APRA's list of Top 30 Australian songs of all time.
 Their debut album, "The Loved Ones' Magic Box" was released late in 1967, which included other hit singles, "Ever Lovin' Man" and "Sad Dark Eyes".
 They disbanded in October and, although the band's main career lasted only two years, they are regarded as one of the most significant Australian bands of the 1960s.
 They reformed for a short tour in 1987 which provided the album, "Live on Blueberry Hill".
 Humphrys lived in London from the mid-1970s until his death on 4 December 2005.
 On 27 October 2010, The Loved Ones were inducted into the Australian Recording Industry Association (ARIA) Hall of Fame.
Free is the second album by English rock group Free, recorded and released in 1969.
 The band had spent time touring after their debut album "Tons of Sobs" the previous year, and there is a marked difference in the musicianship of the band as well as Paul Rodgers's voice.
 Whereas "Tons of Sobs" had been produced by Guy Stevens, "Free" was produced by the head of Island Records, Chris Blackwell.
"Taurus" is a rock instrumental by American rock band Spirit, originally released on their self-titled debut album in 1968.
 The track, composed by guitarist/singer Randy California, was recorded in November 1967.
 It has been alleged that Jimmy Page borrowed the descending guitar figure from "Taurus" for Led Zeppelin's signature song "Stairway to Heaven".
 Led Zeppelin opened for Spirit in an early American tour, providing the possibility that Led Zeppelin had heard the Spirit song before "Stairway to Heaven" was written.
 In the liner notes to the 1996 reissue of Spirit's debut album, songwriter Randy California writes:
