The Slime Buckets are a local band that started playing for free at various local bars and clubs as they try to gain experience and exposure. Swifty Lamar booked the band at many dierent venues for more than two years as the band's unpaid manager. Finally, in the past two months, Swifty was able to book the band at clubs that paid the band a fee for its performance. Last night, Swifty insisted that the band pay him a commission on any fees it collects for future performances; the band refused and fired Swifty. This morning, Swifty went to The Bunkhouse, a bar at which Swifty had previously booked the band to play for free and convinced the manager: (a) to hire the band to play tonight for $500.00; and (b) pay Swifty $100.00 in advance. Swifty left The Bunkhouse with the $100.00 and never told the band anything.

Are the Slime Buckets obligated to perform at The Bunkhouse tonight? Explain your answer.
