Gastank was an English television show that aired between 1982–1983 in the United Kingdom on Channel 4.
 Hosted by former Yes keyboardist Rick Wakeman, the show featured a mix of interviews with 1970s musicians and impromptu performances where the guest artist would join Wakeman and his house band in playing re-arranged versions of their classic songs, or entirely new pieces created for the show.
 The format was very informal with the setting likened to a bar where Wakeman would interview the guest over a drink or two followed by their performance in front of a small studio audience sitting in groups at tables.
 Wakeman would frequently cite the show as an opportunity for musicians from different bands to get the opportunity to work together.
 During its run, the show featured guests as diverse as Ian Paice, Steve Hackett, Andy Fairweather Low, John Entwistle, Godley and Creme, Eric Burdon and Phil Lynott.
