In the 1980s to early 1990s, there was a CBS imprint label in the US known as CBS Associated Records. Tony Martell, veteran CBS and Epic Records A&R Vice President was head of this label and signed artists including Ozzy Osbourne, the Fabulous Thunderbirds, Electric Light Orchestra, Joan Jett, and Henry Lee Summer. This label was a part of (Epic/Portrait/Associated) wing of sub labels at CBS which shared the same national and regional staff as the rest of Epic Records and was a part of the full CBS Records worldwide distribution system.
Who didn't share the same staff as Epic Records?
