Great find! I think I remember one bootleg from Germany '84 (maybe the Capn's of Crunch bootleg CD) where James introduced Cliff before his solo. James said Cliff was going to show off his new gear, or something like that. He must have been talking about the Spoiler. I will have to try and find the exact show...I always wondered which bass he was unveiling (Aria SB1000 or Alembic), but it must've been the Alembic.
