If I remember correctly, by that time David Pleasance was selling the audio CD "Everybody's Girlfriend", rather than any Amiga hardware/software. He had a new career as a record producer/manager - he was a rather good flamenco guitar player, and his son had a band. I still listen to the CD from time to time, I think it's not at all bad, and had a tenuous Amiga theme to it (hence the title).
There was one later Amiga event, but that was at Hammersmith Town Hall (IIRC). I had a stall there, but I'm not sure I managed to sell enough to make a profit on the weekend.
