Licensing tracks for a Best Of compilation was always going to be logistically difficult. In their twelve-year recording career, Reparata and the Delrons recorded for more than twelve different labels. There had been an unauthorised Best Of compilation in 2001, but it was not until 2005 that an authorised Ace Records compilation "The Best of Reparata and the Delrons" was released. The compilation included most of the singles, and some rarities, B-sides and unreleased material. It was accompanied by a comprehensive illustrated booklet, with some new commentary by Mary O'Leary.
