 During that period, Disley continued to play folk clubs and festivals as a solo performer and also mentored a young Chris Newman, who would establish his own name in the swing jazz, guitar flatpicking and celtic folk guitar fields.In 1978 Grappelli, Disley, and others were invited by David Grisman to contribute the score to the film "King of the Gypsies".Grappelli and Disley had walk-on parts as gypsy musicians and were suitably attired for the occasion, but the soundtrack to the movie was never released.
