You might try to find a MIDI version of Mustang Sally on the Internet, bring it into BiaB then use that bass line. You may have to transpose it to match your key signature. I do things like this in my DAW so others will have to give you the exact BiaB method to achieve this.

Good luck.

When you are at the checkout line and they ask if you found everything say "Why, are you hiding stuff?"
