I love instrumentalists to play on songs I sing--obviously not all--chanteys don't lend themselves to that approach. But there are lots of songs which do--and if a song is good, I like it to last--like any pleasurable activity. Many songs are just enriched by letting instrumentalists take breaks--and it's great to hear them. Of course it's essential for all concerned to keep a steady rhythm if there's accompaniment.

Similarly, it's very possible to compliment a song in accompaniment--just don't double the melody---and don't overwhelm the song. And instrumentalists have to realize when a singer wants to be flexible in timing--and not chained to a steady rhythm.

I will have to admit I'm more vocally oriented--and can get my fill rather soon of, say, a series of bluegrass instrumentals--with no vocals.

And if that happens I will definitely go elsewhere.
