This may have been raised before, but I couldn't find any specific reference (I'm not Ricardo !) so I'm asking anyway:
At Royal Festival Hall the TPK was played for the first time i.e. the Cock version. They didn't play it at the next gig at Paradiso 3 days later, but they opened with it in Leicester a week later. What was that version like? Had it progressed to the 'proper' version? Was it an instant change or was it a slow progression? Plenty dates after the RFH but the next one I've got is in December 1985 by which time it definitely was the version we all know and love.
