In the late 1970s, children's audio label Peter Pan Records produced a series of Scooby-Doo recordings in collaboration with Hanna-Barbera, most notably book-and-audio sets (i.e. a storybook or comic book with an accompanying record or audio cassette that plays out the book's story.) These recordings usually featured many of the actual voice cast members of the time currently voicing the gang, including Don Messick (whom usually would also do the opening narration in his natural voice), Heather North Kenney, Pat Stevens and Frank Welker as their respective characters. In the read-alongs, Shaggy Rogers was voiced by Duncan Robertson instead of Casey Kasem, whom did reprise the role for the 1978 LP releases. None of Hanna-Barbera's sound effects or music are used on these recordings; the music score is mainly made up of tunes from stock music libraries. These recordings also marked the earliest use of the name Mystery Inc.
Titles released as 45-RPM book-and-record sets (later also released on cassette) include:
- Scooby-Doo and the Mystery of the Sticky Money (1977)
- Scooby-Doo and the Mystery of the Strange Paw Prints (1977)
- Scooby-Doo and the Mystery of the Ghost in the Doghouse (1977)
- Scooby-Doo and the Mystery of the Rider Without a Head (1977)
The initial two stories were also released together as a "Deluxe Book and Record Set" simply entitled Scooby-Doo, with both stories on a single 12" LP record, and a gatefold booklet with comic illustrations.
Additional LP releases include:
- Scooby-Doo: 3 Stories (1977, featuring the Sticky Money, Strange Paw Prints and Ghost in the Doghouse stories; also released as a Picture Disc record)
- Scooby-Doo and His Friends (1978, featuring the stories Scooby-Doo and the Bank Robber and Scooby-Doo and the Cookie Caper)
- Scooby-Doo: Exciting Christmas Stories (1978, featuring the stories The Mystery of the Missing Santa and Trouble at Santa's Workshop)
