Apparently this is an evening of musical theatre songs taking place at the St Martin in the Fields crypt. The show features four "highly talented lead or understudy singers from current or recent hit shows" but no names are given.
Has anyone attended this kind of event in the past? There is some audience feedback on their website as it seems that (judging from a review on another website) a similar series of shows was scheduled 2 years ago but again I didn't manage to find information about the performers or the programme.

(I looked for a relevant post, but I didn't find any).

A friend of mine has been a couple of times and said it's great.
I've been to the cafe many times and it's really nice. Bet the acoustics are amazing.

I have been to a couple of classical concerts and it’s a lovely venue. Would definitely consider going to more concerts.

This is a really fun evening in a lovely venue - good food and drinks as well. The only negative for me is that the accompanying music is playback, and I miss live musicians. But still an excellent night out.
