Bell was briefly featured in a 1986 BBC documentary, "The Celts", in which he discussed the role and evolution of the harp in Celtic Irish and Welsh society. Derek Bell also appeared with Van Morrison at the Riverside Theatre at the University of Ulster in April 1988. An hour-long BBC special was broadcast in which Derek Bell talks extensively as well as accompanying Morrison on several songs including "On Raglan Road". The video is available on YouTube in full "VAN MORRISON - In Conversation and Music 1988". Apart from this, video of him only exists in minor interviews and performances with The Chieftains.
