"Northern Lights", which became a Top 10 hit on the U.K. charts, was the band's best selling single.
A shortened recording of "Back Home Once Again" was used as the theme song for the short-lived 1977 British TV series The Paper Lads.
Drummer Terry Sullivan had his first songwriting credit with the band on the title track. He was responsible for the basic tune to the song's extended instrumental intro. This was based on a song he wrote on guitar in 1971.
