One of the myriad "Get Back" session compilation bootlegs was "The Black Album", a three-LP set from the 1980s in a memorable package (although the material has since been bootlegged in superior sound quality). In the early 2000s, Yellow Dog Records created "Day by Day", a 38-part CD series the majority of the Nagra tape recordings, with improved audio quality compared to earlier releases. In January 2003, nearly 500 of the original Nagra tapes were recovered by police in England and the Netherlands, with five people arrested.
