A1) Maid In Heaven
A2) Bring Back The Spark
B1) Blazing Apostles
B2) Jet Silver & The Dolls Of Venus
All four tracks were album tracks, one taken from each of their four albums released up to that point.
The Hot Valves ep was the seventh Be Bop Deluxe single issued during the band’s existence. The EP came in a picture sleeve (the first of their singles to do so). Promo copies exist with the words "Demo Record Not For Sale" and a large 'A' printed on the label.
"Maid in Heaven" was the track used to plug this EP, which finally earned the band a minor hit, although it deserved to peak higher than No. 36. Both "Jet Silver and the Dolls of Venus" and "Maid in Heaven" made it onto the Singles As and Bs compilation (1981) on the basis that they had also been issued as singles in their own right.
The EP is long deleted, but all four tracks can be found on the Futurist Manifesto 1974-1978 box set (2012) - both in physical form and as a digital download.
