Rematch marks the first LP release of the studio version of "I've Done Everything For You". The song was originally recorded live and released on the album All Night Long. In 1979, the studio track was released as a b-side to Sammy's single of a cover of (Sittin' On) The Dock Of The Bay.
All the tracks are taken from Sammy's five Capitol studio albums except for the aforementioned "I've Done Everything For You" and "Bad Motor Scooter", which is the live version found on All Night Long.
The cover depicts a mock-up of a supposed boxing match poster advertisement. This represents Sammy's own early career aspirations to follow in his father's footsteps as professional prize fighter. The "main event" in this ad is between Sammy and a fighter named "Roy Scarlet"; a euphemism using Sammy's actual middle name, Roy, and "Scarlet" which would be the equivalent of "Red" for Sammy's "Red Rocker" moniker.
A second billing is also depicted on the poster, John "Little Red" Galt vs. Bill Church. While Bill Church was clearly the long-time bassist in Sammy's band, it is unclear whether or not John Galt refers to the Atlas Shrugged character.
