The group's debut album The Lord's First XI, released on the Acid Jazz Records label, has been championed by Paul Weller, Mark Lamarr, Robert Elms and Gary Crowley, and has seen Large working with a range of soul singers, including Clem Curtis of The Foundations, Dean Parrish, Linda Lewis and The Peddlers' Roy Phillips, as well as the more contemporary talents of Squeeze's Glenn Tilbrook, Andrea Britton and ex-Freakpower trombonist Ashley Slater.

During a short break from Squeeze starting September 2010, Large was temporarily replaced by Steve Nieve (previously of Elvis Costello and the Attractions), before re-joining the band for a performance at the Royal Albert Hall, as part of the annual Teenage Cancer Trust concerts on 22 March 2011.
