Writers might find this an interesting example. An improvisation by Zulu musician Solomon Linda in a 1938 recording session produced an 11 note 'phrase' went on to make millions (estimated £16 M in 2000) over the next 70+ years but the 'author' got 10 shillings for the recording fee and then maybe $1000 from Pete Seeger in the sixties before dying in poverty in 1962.
One slight annoyance, the episodic nature/repetitive structure of the programme suggests it was designed for insertion of ads if sold beyond the BBC. I'm sure much of this could have been 'edited out' for the BBC broadcast.
