Uptown Funk - fun, when someone requests a song, you give it a shot.

Someone requested Bruno Mars Uptown Funk at a "Doo Wop dinner dance", just because one of his albums is Doo Wops
& Hooligans doesn't really make it an oldie but it sure is a fun song. Bruno Mars has that throw back style and I believe he is one of the most talented true "Entertainers" in the scene today.
