I put the Lew Stone on because somebody complained that I hadn't included him to date. He was one of the biggest names in the country in the thirties fronting a big band, but by the late 50s the BBC decided that he was too expensive and if he wanted to continue broadcast, he would have to downsize - hence the sextet, which did a couple of hundred broadcasts. I've been in Lew Stone's home and played his piano! He was actually playing the celeste on this broadcast with Gordon Langford on piano. Lew Stone died in 1969 but his widow only died a few months ago aged 101. A couple of years ago she attended the official launching of the Lew Stone biography in London and around that time Radio Two did a couple of programmes about his career.
Although I preferred his bigger band, I find the sextet quite pleasing and must say I can't find anything wrong with the percussion - but we all have our own preferences.
Glad you liked The Banjoliers, Logjam. I have loads of recordings of them. They were always regarded as the best of their kind - possibly because they were very versatile, many of their players being better known as guitarists.
The announcements are quite clear on this pair of broadcasts, but as you say, some of them do appear to be rather quiet. The BBC used to lower the volume of the signature tune at 15 seconds in, for the announcement to be made, but occasionally the continuity announcer would forget and speak too early - and therefore not be very audible..
