Royal Festival Hall, London
4. Over the rainbow
This was recorded off air in mono when it was broadcast in 1992. The announcer says there would be an interview with KJ between the two long improvised pieces but there is no sign of a break in the recorded performance. There is a cut before the encores, however, so I suspect that's were it was. Anyway, I didn't record it.
Converted to flac in Magix ACL. Sample in comments.
