In these strange times it might be a thought for Mr. B to seriously consider a paid concert on line through YouTube or some other media platform.
The combinations are endless, the regular band, a power trio of oldies, RCFP, etc. Understanding that Mr. B and his bands safety is paramount, it surely would be possible to maintain their social distancing and perform. Sanity for all of us, revenue for the band members, and a smile on everyone's face.
This might also be something that they would consider every six (6) months or so in the future as a supplement to, not a replacement for the current tour performance. I understand the long term financial considerations, but I watched the original Royal Albert Hall performance 5 times on PBS and still bought the DVD...and the CD (before I learned how to rip music from DVD's).
Just a thought....
