Alan Collins
From Tardis Wiki, the free Doctor Who reference
Alan Collins was working for a music company in the late 1980s when he first met the Fifth Doctor and Nyssa. They were on the trail of a music record that held the power to release the Voice onto the Earth.
Collins joined forces with the Doctor and Nyssa after discovering the record was in fact his own.
After this adventure Collins was given a new view of life thanks to what he had seen with the Doctor. (PROSE: Tweaker)
