I would like to add that booking a solo is a lot easier than booking a duo, especially if you have identified a market such as heath care facilities. It's tight this year to maintain prices, let alone try to sell a duo at an even higher price.
I speak for myself, but feel many would prefer to play with other humans if the circumstances and economics were different.
And lastly, it seems a good number of us are established in our lifestyles and prefer not deal with many of the inherent hassles of playing in a group or in public venues, as many have done in past "lives".
