Gregorian Chant at San Miniato?

How confidant can we be that there will be a 5:30 Gregorian Chant recital at San Miniato on any given day? Also there is a limo service on Viator that will take you to San Miniato to take in Florence at night and the recital, but it's expensive and you are picked up at 6:30 pm, so I'm skeptical. Any advice on the recital or how to get to the church on our own would be much appreciated.
