In 1990 he spent time writing and producing heavy rock band London Quireboys's "Little Bit of What You Fancy" (1990) which gave him singles chart success and Canadian rockers Glass Tiger, who achieved international success and platinum selling albums. They were also awarded three Juno Awards, received in Canada. In 1993 Cregan was reunited with Stewart to record "Unplugged...and Seated" which was also filmed by MTV and featured a guest appearance by Ronnie Wood. This recording became Platinum three times in both USA and Canada. In the same year Cregan recorded Van Morrison's song "Have I Told You Lately" (1993) with Stewart, which became a number 1 hit in UK and had top twenty success elsewhere. Cregan's biggest concert appearance with Stewart was on 31 December 1994 at Copacabanain Rio de Janeiro, where they appeared in front of a total estimated audience of over 3.5 million. The Guinness Book of World Records states that this was "the staging of the largest outdoor concert in history".
