London: British rock band The Beatles are to release 59 rare and unheard recordings in a bid to stop their copyright protection expiring.
The digital compilation includes BBC sessions, four alternate takes of `She Loves You` and five of `A Taste Of Honey`, reported BBC online.
EU law protects songs for 70 years after they are recorded, but only if they get an official release. Otherwise, copyright lasts 50 years.
If the Beatles chose not to release the recordings before the end of the year, it would mean other record labels could theoretically put them out and profit from them.
The band`s 1962 debut single, `Love Me Do`, arguably slipped out of copyright last year, before the EU`s copyright extension was signed into law.
