I have the 10CD set (thanks to PeteB) that includes everything from 1936 to 1945 and, listening across the discs I feel that Mosaic made a big mistake leaving out most of the vocal sides. While admittedly many of the songs are quite trite, the singing - Helen Forrest in particular, isn't - they also include some of the best writing and soloing. They also provide a welcome change of pace and really reveal another dimension to Shaw's music. I wouldn't want to be without 'I Didn't Know What Time It Was', 'Deep Purple', 'Day in Day Out' 'Gloomy Sunday' 'Don't Fall Asleep' or 'All in Fun'
Now if I could just get hold of the Mosaic booklet.....
