When do this singing group appear outside Mare Nostrum?

There was a brilliant group singing outside Mare Nostrum last year (facing out onto the street).
Do they still sing there? If so, which night?
Thanks. :)

I'll take it that they don't appear anymore then? :dontknow:

I was out in March and was staying at the Mare Nostrum complex. Can't say I saw them
