The album has been repackaged and reissued many times. Two of the significant reissues are "Procol Harum...Plus!", a 1998 CD compilation on the Westside label including all the songs from both the Deram and Regal Zonophone release, plus "Homburg" (the group's second single) and nine additional tracks from the period; and a monaural audiophile vinyl LP edition released in 2003 by Classic Records, with yet a different track order, including "Homburg" as the opening track and without "A Whiter Shade of Pale" or "Good Captain Clack". The set includes bonus singles of the original monaural and alternate stereo versions of "A Whiter Shade of Pale". A 2009 remaster by Salvo Records, using the original mono masters, was released, with bonus tracks including the singles "A Whiter Shade of Pale", "Homburg", B-sides and alternate stereo takes. However, many of the tracks are played at a higher speed. A 2015 remaster by Cherry Red Records expands the album into a 2-CD set.
