I’ve always felt that some of Ronnie Scott’s finest work was with the sax section of the Clarke/Boland Big Band, where he was featured fairly frequently in solos. So pretty well all of those MPS albums really.
I think Acrobat have done a collection of his early Esquire releases, which are well worth a listen. Also the Jazz Couriers stuff of course.
I’ve always felt that he was strongly influenced by Hank Mobley and heard that he used to get all of Hank’s Blue Note albums when they came out. He’s in print also as saying that he disliked studio recording as it didn’t capture him well. Having said that, ‘Serious Gold’ on Pye is really good, as is that live CD put out by Acrobat with Mike Carr and Bobby Gein of a mid 70s pub gig in Wiltshire (albeit a location recording, not audiophile).
Was fortunate to see him play at his club quite a few times and hear some really fine playing, in some excellent bands. Generally, if there was a US main act on his band would often open the show. The first band of his I think I saw was the one with Louis Stewart on guitar, followed by the quintet with Dick Pearce on trumpet/flugelhorn. Later on he added Mornington Lockett on second tenor. Used to hear that Mobley influence pretty strongly, although some Getz influence also. As you mention, he could build up those long solo lines logically and to great effect.
Also an incredible stand-up comedian. Always hilarious, although incredibly his own opinion was that he was embarrassing and not funny. In truth, totally the opposite.
