Depending on the crowd, you may need to have the "old chestnuts" .. Margaritaville, Brown Eyed Girl, Ol' Time RnR, My Girl, etc... and Others like Mustang Sally, In The Midnight Hour, I Feel Good ...
You can even do some of the old standards such as "Stormy Weather" in a 'shuffle/blues/boogie' style ... (did that one on Friday and it went over well ) ...
If it's a 'party', I think you want to keep the tempos up ...
