I think it was in Barcelona on the Elevation tour. I think I still have the mp3 of it.. unfortunately I don't know how to send it.... You can prolly find it on New Media tho.
Technically 11 O'Clock is not a B side. It was released as a single and Party Girl was the B side for it.
Spanish Eyes has been played on several tours. Very rough versions were done on Zoo and Elevation.
The best versions of Spanish Eyes were done during the Joshua Tree tour. Some absolutely rocking versions were done then. Get the Back In Denver 11-7-87 boot as there is a high quality version there. Also the 2nd Munich 87 show has a great version as well.
