Here are rips of 172 Boosey & Hawkes 78s from the early 60s which originated from the Internet Archive but which I have cleaned up and edited. I am pretty sure none of them have been shared here before. They are archived into four parts. A screenshot of the contents of each part is shown on the accompanying PNG files.
