After the breakup
Following the breakup, the only album to feature all four Beatles (although not on the same song) was Ringo, a 1973 Starr solo album. Any hopes of a reunion were dashed when Lennon was murdered by Mark David Chapman, a mentally ill fan, on December 8, 1980. However, in 1981 the three remaining Beatles (with Linda McCartney and Denny Laine doing backing vocals) recorded the song "All Those Years Ago", a tribute to John Lennon written by George Harrison and released on his album Somewhere in England. Another virtual reunion occurred in 1995 with the release of two original Lennon recordings which had the additional contributions of the remaining Beatles mixed in to create two hit singles, Free as a Bird and Real Love.
Three volumes (six CDs in total) of unreleased material and studio outtakes were also released, as well as a documentary and television miniseries, in a project known as The Beatles Anthology. On December 15, 2005, McCartney and Starr, along with the families of Lennon and Harrison (who died 29 November 2001) sued EMI in a royalties dispute in which Apple Corps claimed EMI owes The Beatles £30 million.
They remain enormously popular. In 1995 and 1996, three Anthology collections of CDs were released, each containing 2 CDs of never-before-released Beatles material, based on the Anthology documentary series. 450,000 copies of Anthology 1 were sold in its first day of release, the highest volume of single-day sales ever for an album. In 2000, a compilation album named 1 was released, containing almost every number 1 single released by the band from 1962 to 1970. The collection sold 3.6 million copies in its first week and more than 12 million in three weeks worldwide, becoming the fastest-selling album of all time and the biggest-selling album of the year 2000. The collection also premiered at #1 in the United States and other countries.
