He has also recorded albums as a solo artist, and performed as an actor in musical theatre productions in both the West End and on Broadway.

He would listen to his mother's Barras-bought 8-track record collection of Burt Bacharach and Hal David, but it was the soul genre of the selection that drew him in.

"[1] In 1982, at the age of seventeen, McLachlan, who was training to be a painter and decorator, formed a band with three friends from Clydebank High School in his hometown.

In 2002, he hosted and sang in Girls' Night Out, one of a week of shows in aid of the Teenage Cancer Trust, at the Royal Albert Hall.

This led to him, in 2002, being offered the part of Billy Flynn, the lawyer in the musical Chicago in London's West End and, in 2004, on Broadway.

At the end of June 2004, the reformed band went to a secret location to record tracks for a new album and to prepare for a UK tour.

Pellow went on tour during October and November to support the album, with a helping hand from regular Wets contributor Graeme Duffin.

Pellow won the second series of the prime-time BBC1 show Just the Two of Us, which began on 2 January 2007, partnering actress Hannah Waterman.

In May 2008, Pellow appeared in Sir Tim Rice's concert revival of his hit musical Chess, playing the "Arbiter".

He performed the role of The Sung Thoughts of the Journalist in the 2012–13 arena tour of Jeff Wayne's Musical Version of The War of the Worlds – Alive on Stage!

Pellow appeared as Che Guevara in Evita on tour around the UK in 2013, and subsequently reprised the role in a limited-run West End production of the musical from 15 September 2014 at the Dominion Theatre.

Pellow played the narrator in Willy Russell's Blood Brothers at Hastings White Rock Theatre between 23 and 28 March 2015.

[11][12] In October 2003, Pellow's then-ex-bandmates attended his mother's funeral, a show of support that touched the grieving frontman.
