What a Mann was Manfred Mann's first compilation of material from their Fontana sessions. Issued in March 1968, the album appeared at a time when Manfred Mann's commercial appeal appeared to be waning. Between the release of "Ha Ha Said the Clown" in early 1967 and "The Mighty Quinn" in 1968, the group had only scraped a number 60 hit with a jazz instrumental entitled "Sweet Pea." The follow-up single to this, "So Long Dad," failed to chart, as did their Instrumental Assassination EP.
