Differing slightly in terms of the track line up (an early rarity is featured on the Rhino disc along with the b side of the band's last single which isn't available anywhere else), Greatest Hits substitutes two album tracks for two rarities included on the Rhino disc. The original Rhino release sounded muddy and indistinct compared to this collection. You Didn't Have to Be So Nice and Daydream both benefit substanially by the improved sound.
Always an under rated band, The Spoonful finally got their overdue recognition when they were inducted into The Rock'N'Roll Hall of Fame in 2000. The Spoonful managed to create an impressive body of work within a short span of time (they were together with Sebastian as a member for less than four years). Recognition has eluded the band for far too long. Greatest Hits (along with the re-release of Daydream and Do You Believe In Magic) has gone a long way towards redressing that imbalance.
The sound quality is better than your memory of the original sound. I have the "not cleaned up and remastered" CD of their greatest hits and this was worth the money for the better sound.
Be honest, we all felt a little guilty listening to the Spoonful and enjoying their music. We felt we should be more serious and ponder great thoughts like "Draft Beer, Not Students." That was the 60s, this is now. They are still just flat-out fun to listen to!
