Barham has played or collaborated with a number of other significant figures in the entertainment industry, including Elton John, André Previn, Roger Daltrey, Gene Pitney and Badfinger. With Simon Leng and former Splinter songwriter Bob Purvis, he formed Inscribe Music in 2007, a company providing services in composing and producing music. Late that year, as part of an initiative by Inscribe, Barham worked with Newcastle College in the north-east of England on a recording of Purvis's song "Sail Away", for release as a single to benefit Cancer Research UK. In line with his past achievements in promoting Indian music, the company sought to establish partnerships in the Indian film industry.
