The Yardbirds 1963. Crawdaddy Club impresario Giorgio Gomelsky became the Yardbirds manager and first record producer. Under Gomelsky's guidance the Yardbirds toured Britain as the back-up band for blues legend Sonny Boy Williamson II in December 1963 and early 1964, recording live tracks on 8 December and other dates. The recordings would be released two years later during the height of the Yardbirds popularity on the album "Sonny Boy Williamson and The Yardbirds". After the tours with Williamson, the Yardbirds signed to EMI's Columbia label in February 1964, and recorded more live tracks March 20 at the legendary Marquee Club in London.
10cc inspired writing. Every member of 10cc was a multi-instrumentalist, singer, writer and producer, and the writing teams frequently switched partners, so that Godley/Gouldman or Creme/Stewart compositions were not uncommon. After Godley and Creme left the band in 1976, Gouldman and Stewart were the main creative forces behind 10cc. Stewart left the band after 1995 and Gouldman continues to lead a touring version of 10cc. Most of the band's albums were recorded at their own Strawberry Studios (North) in Stockport and Strawberry Studios (South) in Dorking, with most of those engineered by Stewart. 10cc was co-managed by Ric Dixon and Harvey
