20 Greatest Hits was released to mark the 20th anniversary of The Beatles' first record release, "Love Me Do," in the UK in 1962; it was the last Beatles album to be released with variations in the US and UK versions (some Beatles hits in the US weren't released as singles in the UK, such as "Eight Days a Week" and "Yesterday"). The American version of this LP was released in Canada, although the track list does not reflect the number ones from that country, as "Can't Buy Me Love" only reached #3 on the CHUM singles charts, and omits the Canadian #1 hits "All My Loving" and "This Boy."
