At the risk of being annoying*, I'll repeat myself (then absent myself from further comment): The History Of The Dave Clark Five. You can find copies of this long out-of-print 2-CD set for a reasonable amount online. It's got fifty (50) tracks -- in my opinion, pretty much everything great the DC5 ever recorded. And, it sounds slightly better than the two more recent compilations (although I'm not sure that any were taken from original master tapes -- I may be wrong.) *Not that that has ever slowed me down.
