I saw them in Birmingham in 1977 at a club called Barbarellas. It was a very famous punk club in those days. I think I saw them there at least three times there. SOme of my memories are,
-John wearing sort of wolly jumper. At the end of the show it was pulled all over the place.
-I remember John would pick up a rather large strobe light and hold it very close to his body and dance all over the place.
-Another time he came out in this very nice suit. I dont remember what song it was but at one point he was singing very serenely and someone gobbed on his left shoulder.
I think at one point the punks were pretty confued because "Young Savage" was almost a standard "kick the can" punk song so I think they expected all their songs to be rock-rock and YS.
I can also remember them walking off stage at the end of Distant smile ( I think) with all the feedback making this horrible moise (it might have been artificial life??)
