Mother of the Bride is hired to play a divorce party, but there's a sentimental catch. The couple splitting up is the same couple that hired the band to play their first wedding. Determined to be "wedding whisperers" and keep the couple together, Tommy and the guys have to go rogue from Rutherford's event plan, even if it means losing their jobs. Donald Faison, Ashley Williams, Joanna Krupa and Train lead singer Pat Monahan guest-star.
