4 must have hours of baby boomer music?

I'd go with all Dan and mix up the tracks..
Reeling in the Years......

great suggestions. Some scared me a bit, but many brought back memories. That Rhino compilation cd sounds great. Probably has all the goodies that were mentioned. thanks guys, warren

If you have cable TV most systems have music "stations" with a 60s or 70s niche.

Most of us geezers got weaned on radio (not hearing a whole album at once), so yeah i think the Rhino thing may be a good way to go, (also this way, no one at the party would have to put up w/ a whole album of an artist that they hate). 70's Smash Hits vol. 2 is cool. Spirit in the Sky/ Little Green Bag/ Ride Captain Ride.
PS- I'd try to sneak some Ventures in there.

if you are buying cd's just pick your favorite artist.
Most have reissued a "best of..." or "favorites cd" which are ideal for parties. most of which can be obtained on short order from amzon.com. enjoy
