Jack - we always play music at intervals. ( We've recently upgraded our equipement from a tape desk to a CD player). Barn dance intervalls tend to be longer than concert ones, and people like to hear a bit of background while tucking into supper and buying raffle tickets. However, we've found that tune sets are best as people are not concentrating on words.

At wadebridge festival the young man played Poozies Cds - so we could enjoy the music before the concert started and while buying pasties at the interval ( excellent pasties).

The Barge pub in Gillingham ( our local folk music pub ) plays a good selection of music at the interval - often including local artists. It gives us time to tune up and say hi to all our friends in the audience.

Long live good interval music.
