He then played with Brian Auger's Oblivion Express, appearing on the band's first three albums together with future Average White Band drummer Robbie McIntosh, Mullen then joined Kokomo and later toured with the Average White Band.
It was while both musicians were touring the United States with AWB in the mid-70s that Mullen met tenor saxophone player Dick Morrissey, and throughout the 1980s, he found critical notice as joint leader of the British jazz funk band Morrissey–Mullen.

In 2014, he featured prominently on the Citrus Sun album, 'People of Tomorrow', produced by Incognito co-founder, Jean-Paul 'Bluey' Maunick.
Mullen has won many British music awards including "Best Guitar" in the British Telecom Jazz Awards (1994, 1996 and 2000).
