saw Pat in 1980 Harrisburg.
First 2 rows of seats were Empty through out the concert.
Perhaps they were afraid someone would attack her

of course Maybe they were for special Guests that I don't remember
but we were 3rd row Center. no assigned seating in advance.
First Time I saw her walk out on stage I was Shocked how Tiny she was .

Backup was some guy sitting in a chair with a Flat Guitar.
I don't think he was anybody. and pretty much sucked.
