[edit - upon further review, I guess this *has* actually been reissued a few times, both on CD and LP]

When we launched our Elektra reissue program, we honestly didn’t think we would land this legendary 1966 rarities compilation, because it boasted a couple of big-name artists, the Lovin’ Spoonful and Eric Clapton, who were not known for their association with the label. But the lawyers checked, the label signed off, and here we are, with one of the decade’s most notorious compilations! The Lovin’ Spoonful tracks stem from the band’s almost having signed with the label; Jac Holzman states in the notes that it was John Sebastian’s way of making amends, and these four tracks–'Good Time Music; Almost Grown; Don’t Bank on It Baby', and 'Searchin’'–were never recorded by the band, not even in different versions. The Clapton tracks, meanwhile, feature him with Powerhouse, a supergroup composed of Jack Bruce, Stevie Winwood and Manfred Mann lead singer Paul Jones; produced by Joe Boyd, the tracks are 'I Want to Know; Crossroads', and 'Steppin’ Out'. Five Paul Butterfield Blues Band tracks appear here from their ill-fated debut recording session for Elektra: 'Lovin’ Cup; Good Morning Little Schoolgirl; Spoonful', and two that appear nowhere else, 'Off the Wall' and 'One More Mile'. Tom Rush’s 'I’m in Love Again' is an outtake from his 1966 LP 'Take a Little Walk with Me', and Al Kooper’s 'I Can’t Keep from Crying Sometimes' is something of a rehearsal for the later, fuller Blues Project version. A collector’s dream–a 'Collectors’ Choice Music' exclusive!
