I'd be sorry to lose the positive effect a good, well-planned and well-timed change of tune can have in a dance; it's just another tool in the dance band's toolbox, like changes of instrumentation or choice of tune.

A well-thought-out change of tune in the right place is a joy to behold and, of course more importantly, to dance to. Changing tune just to make life more interesting for the band is another matter entirely ...
