For Disney, he provided the voice of Scrooge McDuck from 1974 to 2016, and also voiced Hiram Flaversham in The Great Mouse Detective, and Doctor Cooper in the TaleSpin episode "The Old Man and the Sea Duck". He also played Dr. Winger in The Cat from Outer Space.
He also voiced Mickey Mouse and Merlin in the Disneyland record album An Adaptation of Dickens' Christmas Carol, Performed by The Walt Disney Players, which would be the first and only time that Young voiced them. The album also marked Young's first performance as Scrooge McDuck.
- Although his role as Scrooge McDuck had already been recast in the reboot series of DuckTales, Young was originally going to have a cameo on the new series as a different character. However, these plans were cancelled, as Young passed away before his lines could be recorded.
