The dance music of the '70s and the disco age is popular again thanks in part to TV shows like Dancing with the Stars. Here is an entertaining medley featuring some of the best riffs and grooves from that era. Includes: You Should Be Dancing (Bee Gees), Boogie Fever (The Sylvers), Reunited (Peaches & Herb), That's the Way (I Like It) (KC & the Sunshine Band) and Y.M.C.A. (Village People).
