Stile Antico, the early music choral group, have posted:
We’re really sorry that we weren’t able to sing the second half of our concert in Cambridge tonight. We wish a swift recovery to the lady who fell ill during the interval and would like to thank the audience who waited so patiently while she received attention. We look forward very much to returning to Cambridge in 2016.
The group will be appearing in the BBC Proms Sherlock Holmes concert this afternoon.
