Pratt came to prominence when he was chosen to play bass for Pink Floyd's post-Roger Waters A Momentary Lapse of Reason Tour in 1987–90, and The Division Bell Tour in 1994. He co-performed the lead vocals on "Run Like Hell", "Another Brick in the Wall, Part 2", "Us and Them" and "Comfortably Numb" with Gilmour during the live shows. He also played bass on several tracks on The Division Bell. Tony Levin had performed all of the bass parts on A Momentary Lapse of Reason; Pratt replaced him on the later tour owing to Levin's unavailability. Pratt also toured as part of Gilmour's On an Island Tour backing band, alongside another Pink Floyd member (and his father-in-law), Richard Wright. He also later performed with Gilmour during his Rattle That Lock World Tour in 2015–16. Pratt played bass on Gary Moore's Dark Days in Paradise tour in 1997. Besides working as a bass player, Pratt is a songwriter and composes music for TV and film. As a songwriter, Pratt co-wrote the UK number-one hit "Ain't No Doubt" by Jimmy Nail. He produced, co-wrote and played bass, guitar and keyboards on the music for the 1998 Channel 4 drama series The Young Person's Guide to Becoming a Rock Star. With regular collaborator Dom Beken, he provided the theme music to Spaced, where he also appeared as the character Minty. Pratt also acted in Linda Green and appeared in an episode of the remake of Randall & Hopkirk, starring Vic Reeves and Bob Mortimer. Pratt's father Mike had played the part of Jeff Randall in the original 1960s series. Pratt also played as a regular in the backing band for the BBC Radio 2 musical comedy show Jammin' with Rowland Rivron. Pratt and Jimmy Cauty released a single "I Wanna 1-2-1 With You" as Solid Gold Chartbusters in 1999; Pratt and Cauty (a founder of the Orb) later teamed up with the other original member of the Orb, Alex Paterson, to form Transit Kings. Pratt's one-man music and comedy show, My Bass & Other Animals, debuted in August 2005 at the Edinburgh Festival Fringe; this led to his book of the same name, published in May 2007. Pratt spent 2011 performing stand-up in Switzerland, Australia, and at the Edinburgh Fringe, as well as on a South American tour playing bass guitar for Dominic Miller. In April 2010, Pratt joined the Argentine cover band
