James "Jay" Lewis is a singer, songwriter and multi-instrumentalist from Huyton, Liverpool. He is best known as the current bassist for the band Cast and for a brief spell as lead guitarist during comeback shows for seminal Liverpool group The La's.
Lewis first came to prominence as the lead singer and guitarist in Cracatilla, a trio he had formed with school friend Dave Penswick on bass and neighbor Louis Fitzpatrick on drums. Named after Lewis' mishearing of the volcano Krakatoa, the band released their debut single "What Do I Know" in August 2002. This was followed by the double A-side "You've Got It All"/"Everyman" on 2 June 2003.
After announcing they were reuniting for performances at Summer Sonic Festival in Japan, on 24 March 2005, The La's confirmed their first U.K. shows in over a decade with a new line-up consisting of original members Lee Mavers and John Power, with Lewis on lead guitar and Nick Miniski on drums. While the sets were mostly similar to the band's shows in the late Eighties until 1991 by drawing heavily from their sole full-length album, these shows were also notable for including three unreleased songs, "I Am the Key", "Gimme the Blues" and "Sorry". Besides headlining shows in the U.K., Ireland and Japan, the band also played at festivals including Glastonbury and Oxegen. Lewis' final shows with The La's took place at V Festival in Chemlsford and Stafford on 20 and 21 August 2005.
Following their stint together in The La's, Lewis would become a frequent collaborative partner of John Power in the studio and for live shows, both as part of a backing band and as an acoustic duo. He played bass on Power's third solo album, 2008's Stormbreaker, and is featured on The Mariner Sessions, one of the four discs in Power's The Complete Studio Recordings: 2002-2015 box set released in 2015.
After bassist Pete Wilkinson abruptly left a Cast tour in December 2014, Lewis was brought in to finish the remainder of the dates. When it emerged that Wilkinson had left the band altogether, Lewis became the band's new permanent bassist. He is featured on the band's sixth album, 2017's Kicking Up the Dust, contributing bass, backing vocals, organ and Fender Rhodes.
