I used to belong to the top music morris side in Kent. We had the core of 3 bands within the side. There were quite a few of us, so if we went to a sing around then it did take quite a while to get through us all. However, we only did a few unacomplished songs - and interspersed them tunes. Some of the songs we did were the sort that everybody knew, not just the choras but all the verses too, so there was a chance for everybody to sing.

I have heard some publicans say it was the music rather than the dancing they enjoyed. In the last year I was there, the musicians were booked for the cambridge folk club and the wisdom hospice seperately to the dancers.   

I don't think we are the side mentioned above, as we were more likely to start our own session and then encourage others to join in. It involved a bit of organisation at the do, as I would not have wished the session to deteriorate into wall to wall melodeons, nor wall to wall unaccompanied singers, which I know can happen with morris sides.

I like to think that anywhere the side was booked they got the double advantage of the dancing and the music.
