I, too, am troubled at the lack of readily available Tony Scott "jazz" sides. The RCA LPs go for quite a bit. I was able to find a copy of "Both Sides" for five quid in Edinburgh, tho.
I should think that the rats at Lonehill/Definitive would be putting the RCA & Decca stuff out. They put out some, but I want more! Again, like the Tal Farlow set they put out, I would be willing to cross the line and buy grey market. Only if it is unavailable elsewhere, however.
