All of our performances no matter how many of them you choose will last around 7 to 8 songs which is around 30 to 40 minutes with Banter and guest participation within the show.
Any longer, we find that the groom, best man and father of the bride tend to get a little bit edgy as their speeches are usually after our performance :), we wouldn't recommend any shorter either as we want all of our customers to get value for their money.
