Band in a box or better- "jammer pro".
but for super-fast result get an arranger-play everything -save it to SMF format/or MP3,then use it as backing tracks.Downside of MP3s(transposition and channel volumes can not be readjusted- say you'll be stuck with recorded bass/drums ch volumes),since we can come across with different PA systems).

Or you can just buy/download - SMF(midi files)on the net.

What kind of KB do you have?
