Clearly a potentially formative event for listeners/musicians of your generation, Sidewinder! Alan Barnes said he travelled down from music college in Leeds to hear Pepper at Scott's that week.
Can't work out exactly why I missed it. Maybe having tickets for the Capital Fest diverted me from Scotts that week. Combined with student shortage of dosh, of course. What I do remember from RFH though is that Pepper's brief but glorious rendition of 'Somewhere Over The Rainbow' brought the house down.
I remember Jazz Journal and Melody Maker having major writeups of that Scotts gig, so it was high profile.
