Why are these people smiling?

The BIB editor explains:

Because they're the Westport Folk and Bluegrass Festival committee (l-r: Uri Kohen, Sarah McEvilly, Fergus Kelly, Tim Rogers), the work and anxieties of the 2015 festival are over, and it's been an outstandingly successful event.

The new evening concert arrangements, in particular, made all the difference in the world. Not only were Holy Trinity Church and the brand new Town Hall Theatre splendid venues - it's exhilarating to be in an audience where everyone is enthusiastic about the music. The concert on Saturday night (13 June) was the first major event to be held in the Town Hall Theatre; and it was good to hear appropriate tributes being paid to the Festival in general, and Uri in particular, for what they have done for the town.
