There was a thread on the McEwan Bros a while ago but nobody seems to know what happened to Alex. None of their recordings seem to be available in the UK but there are two CD's available from Smithsonian-Folkways. If you think that's the wrong way round, the best blues and old time CD's come frae Bonnie Scotland!
I'm sure Stan Francis wasn't a professional instrument maker or musician; I used to know what he did for a living but can know longer remember. He lived in or around Roby about 5 miles from Liverpool
