Apollo 100 was a short-lived British instrumental studio-based group that had a hit with the Johann Sebastian Bach-inspired single "Joy" in 1972.The recording of "Joy" as performed by Apollo 100 is a nearly note-for-note remake of the arrangement of Jesu, Joy of Man's Desiring (but with modern pop music flourishes like percussion and bass) recorded by the British band Jigsaw on their 1970 debut album Letherslade Farm.Tom Parker was an accomplished arranger responsible for most of the successful arrangements from the Young Blood catalogue, such as the Top 20 American hit "Chirpy Chirpy Cheep Cheep" and a number of Don Fardon's recordings.
