Jenny,
The only thing I can think of from the 60's could be the Beach Boys and Deep Purple.
Here is a list of oldies you must have for the party... some not so old
Hip Hop Hooray - Naughty By Nature
Jump Around - House Of Pain
Hot Hot Hot – Arrow
(You gotta) Fight for your right (to party)-Besty Boys
Hut Stuff- Donna Summer
Saturday Night - Whigfield
Kung Fu Fighting- Carl Douglas
I will survive- Gloria Gaynor
Tainted Love- Soft Cell
oh
and some Cypress Hill
And for Lander, Jjgold, Journeyman, Railbird and Identity (just in case)
get Y.M.C.A from the Village People, New York City Boy from Pet shop Boys and Vogue from Madona
