I saw Ra and the Arkestra a couple of times in the late 80s - once in Toronto and then a few months later in Boston (pre-stroke). The Toronto gig was particularly good, seemed to go on for ever. He also broke the concert up into self-containes sets - 'Greatest Hits', 'Disney', 'Tribute to Fletcher Henderson', 'More Greatest Hits'. Lots of good stuff - 'Rocket No. 9', 'Sunset on the River Nile' etc.
