Wedding band booking regret ...

So, I have heard the band we've booked online and I don't know if I was just wrapped up in the excitement of booking the entertainment/reading the highly rated reviews, but after re watching videos I'm really not sure if they're that good? We've paid the deposit, so the deals done but my question is...did anyone else feel the same but sounded better on the night? I'm wondering if it'll be better with the atmosphere, everyone dancing and drink in hand, it'll actually be ok? 🤣🙏🤦‍♀️
