After responding to the recent query here on Harry Boyd, I've made the first of a series of updates to my website. This update has added three more Alexander Prince 'Winner' label 78rpms, so you can now download a complete set of all his Winner recordings, which were issued between Feb 1912 and Jan 1914. Research suggests that all these sides were recorded c.1910 and previously release on the Bell Disc label, but until I find more definite release dates for Bell discs, they are indexed by their Winner release dates. The Prince audio page is here
An update to the Prince discography is also well advanced. Many more release dates - especially of cylinders - will be added, plus direct links to the audio where I have it.
