Gwen,are you checking out oldies record stores? If not,that's your best bet. I know you wont find it in yard sales or Goodwill/Salv. Army. I do know that it's nowhere to be found here in Phx. ! After my exhausting GL search last year,I think I picked every possible place clean (of really good copies). I didn't see any S.C. + , sorry!
Keep lookin',it'll turn up when you least expect it! Later!
