Once Animals' reissues began occurring during the compact disc era, Allen Klein, by then owner of ABKCO and the rights to this material, dictated that the "correct" British version be used on all reissues and compilations everywhere. Thus, as US radio stations converted from vinyl records to CDs, gradually only the British version became heard. Some collectors and fans in the US wrote letters of complaint to "Goldmine" magazine, saying they believed the US version featured an angrier and more powerful vocal from Burdon, and in any case wanted to hear the song in the form they had grown up with. The 2004 remastered SACD "Retrospective" compilation from ABKCO included the US version, as did the budget-priced compilation "The Very Best of The Animals".
