When I heard it the first time, I thought Central Line was an All- American band of the early '80s since they released a single, "Walking into Sunshine", but I never realized they were British.
Here's the story:
The band was formed in March 1978 and signed with Mercury Records in early 1979 by John Stainze. The original founding members were Steve Salvari, Camelle Hinds, Francis Lipson and Henry Defoe. Hinds, Francis and Defoe were previously in a band called TFB (Typical Funk Band), which contained members that would form Light of the World.
TFB also contained drummer Errol Kennedy, who later joined Imagination. Salvoi joined TFB following the departure of Kenny Wellington in late 1976 as their second keyboard player and band members performed at Salvari, Hinds, Francis, Defoe and Kennedy.
The band played for about a year and then broke up. Francis and Defoe went to work with a bassist who was at Boney Me Salvari and Hinds staying together to work on various projects.
In early 1978, four of the TFB members rejoined and expanded the previous format by recruiting Linton Beckles (born Linton Charles Beckles, December 17, 1955 - April 3, 2015) and Kim "Jake" Le Mesurier (oldest son). English actors John Le Mesurier and Hattie Jacques and brother of longtime guitarist Rod Stewart Robin Le Mesurier). The band decided that they needed a new identity, and Defoe came up with the name Central Line because the band was running after a funk and soul center line.
