Beatles Vs. The Offspring (Music copyright case)

In 1968 the Beatles had made a song called "Ob-La-Di, Ob-La-Da" on thier self-titled albulm. The song was written by Paul McCartney. Later on in the year 1998, The Offspring (an American punk rock band)released a multi-platinum album called "Americana". In the albulm (11th track on the record) they have a song called "Why Don’t You Get a Job". In the song "Why Don't You Get a Job" they use the melody and rhythm of the song "Ob-La-Di, Ob-La-Da" (which was the Beatles)! There has been no indication that The Offsprings The Beatles or Simon and Garfunkel any monetary compensation for using their work. In the end The Offspring said their song was a tribute to "Ob-La-Di, Ob-La-Da".
