Renwick is credited as the co-composer of
Elton John's song "Dreamboat". The song was released on the "
Kiss the Bride" single in 1983, but was most likely recorded in the late 1970s, when Renwick was briefly a member of Elton John's band, recording with him on
A Single Man and playing with him in John's 1980 concert in
Central Park, New York. In 1984, Renwick toured with
Roger Waters during his
The Pros and Cons of Hitchhiking tour. Among the other musicians in Waters' band was
Eric Clapton, with whom Tim toured the following year, on Clapton's
Behind The Sun tour. He appeared as a member of Clapton's band at the
Live Aid Concert 13 July 1985 in
Philadelphia, Pennsylvania. In 1987,
David Gilmour invited Renwick to tour with Pink Floyd as a session musician, and recordings from the August 1988 shows were released in the double live album
Delicate Sound of Thunder. This makes Renwick, along with
Michael Kamen,
Patrick Leonard and
Jon Carin, one of the few musicians who performed with both Waters and his former bandmates after Waters had left Pink Floyd. Renwick joined the Tex Maniax with Andy Roberts and other ex Wangfords (1984) and
Mike + The Mechanics (1989). Renwick joined Pink Floyd again later on their 1989 European tour, on the 1994 studio album,
The Division Bell, and on
The Division Bell Tour, which again resulted in a double live album,
Pulse. Renwick made a live appearance with the
Alan Parsons Band in the 1998
Michael Jackson Gala (replacing the original guitarist
Ian Bairnson). He recorded with Pink Floyd colleague
Rick Wright, playing guitar on his 1996 album
Broken China. In 2005 he appeared once more with Pink Floyd as second guitarist (and bassist on "
Wish You Were Here") for their
Live 8 reunion. He also played with
Al Stewart at
Cambridge Corn Exchange on 7 October 2013, and again on Stewart's 2015 UK and Ireland tour. == Solo work ==
