For those who don't know.. under UK copyright law any artist can claim their recordings back from a record company after 50 years. The artist is supposed to give one year's notice of intent to the record company (though that may be awkward with record companies who no longer exist).   The record company has to be making that recording available on a reasonable scale under the use it or lose it rule. Copyright on recordings is 70 years for post 1962 issues. After 70 years anyone can issue the recordings as long as they pay royalties on the songs recorded.
