Escala

I'd bought various bits and bobs for my sewing in John Lewis, and was approaching the Grand Arcade exit, when I heard a man with a microphone. I was wary: I didn't want to get caught up in anything, but I wanted to go to the library, and the most sensible way was to go past.

It turned out the man with the microphone was at the tail end of an interview with some girls on the little stage, who had apparently been performing.

I had no idea who the girls were, but the man asked for a round of applause for "the Escala girls". When I got home, I googled them and a bell rang: they're a string quartet version of Vanessa Mae.
