Duet All Night Long is a split EP release by Reel Big Fish and Zolof the Rock & Roll Destroyer. It contains six cover songs of which three are performed by each band. Both Rachel Minton of Zolof the Rock & Roll Destroyer and Aaron Barrett of Reel Big Fish sing on every track, hence the title of the EP. On "Say Say Say", however, the male vocalist is Scott Klopfenstein (the backing singer and trumpeter of Reel Big Fish) instead of Aaron Barrett. Klopfenstein also appears in his usual backing role, including a small bit of the lead during "It's Not Easy".
