Two more Undercurrents shows from Charlie when he was on Capital Radio - a one hour lunchtime show on Sundays from 1980 to 1982 I think. Mostly punk and new wave records from independent record companys. One contains live session from The Shakin' Pyramids.

"The Shakin' Pyramids (also known as Shakin' Pyramids) were a Scottish rockabilly band formed in Glasgow in the late 1970s. The band consisted of Dave Duncan (vocals, harmonica, percussion) James G. Creighton (acoustic & electric guitar, vocals) and "Railroad" Ken McLellan (acoustic guitar, vocals).
During the band's recording career from 1980–1983, they released two studio albums, four singles and three extended plays—one of which was recorded with the late British recording star Lonnie Donegan. A 1983 compilation album was released shortly after the group's disbandment, and a live album followed in 2001. Although the band did not enjoy any major chart successes, their work was generally well received by critics. They earned a fan base through their energetic live performances, which were originally honed on the streets of Glasgow and later exhibited via their extensive touring and a number of television appearances. In recent years, their work has been described as having helped define the short-lived rockabilly revival of the early 1980s."
