Patti Smith - Revenge Of Vera Gemini

[Jerry]

I recently got a tape including a song by Patti Smith - 'Revenge Of Vera
Gemini'. It was credited to be recorded at the NY Palladium, but no date.
I din't understand the introduction, but afterwards she yells 'Blue
Oyster Cult!'. Also, a guy is singing, with Patti doing the female parts
as on BOC's version.
Does anyone know when this was recorded and who is singing / playing with
her?
