Well, Joanne, you opened Pandora's Box, it looks like!

Mary (mg), I have heard of Martin Simpson, but
not for political bias during performances.

Actually, I am reminded of the remark made during my late lamented days singing in a church choir.
One rehearsal evening our director could not be present,
and one of the choir members, a wife and mother with a long-time membership in the church, substituted.
As we were reviewing the hymns for the coming service,
she quietly remarked that

"for some people who come to church,
our singing is the only Gospel they truly hear."
