I bought this compilation because; one, it seem to have all the hits, two, I had never heard their version of (gasp) "Inside Lookin' Out" & three, I wanted a single album & disc that best showcases this group. This does that. The only song that I wish were here is "I'm Mad". I would like to compliment the different record labels for coming together to present what can be legitimately called a 'retrospective'. All too often the fan only gets what that particular label owns. This spirit of cooperation, at the very least, makes me feel like they're doing their best to give the most complete product possible.
