HI Robert. I'm not sure of his other credentials, but I know that he was very involved in Bad Company's 3 big albums in the late '80's/early '90's. Him and Brian Howe (Bad Co.'s singer for those albums) co-wrote almost all of the material, which I thought, and still think, was great. The albums titles are Dangerous Age, Holy Water and Reckless (or something like that, it's the one with How Bout That).
