Produced by Mike Mansfield who was also responsible for two other shows broadcast on the 31st July, Roller Coaster (with The Bay City Rollers) and a Hollies special.
Superpop '76 was intended to be a summer replacement for Supersonic, but it probably lead to pop overload that year with many of Mansfield's other projects shown by London Weekend, including specials with Marc Bolan, Sailor and The New Seekers.
The show was the familiar mix of pop stars with lots of new talent with little or no chance of success.
The show wasn't networked by ITV and might have only been shown elsewhere by Grampian.
According to a January 1977 report in Billboard magazine London Weekend would no longer screen the show saying that the remaining shows were not suitable for company needs. They also claim the shows were produced with financial assistance from record companies.
