There have been many comments about how Beatles songs like "Yesterday" are among the most covered songs in history. This led me to wonder, which artists/groups have not covered any songs by The Beatles. For purposes of this thread it should be artists who have had the opportunity to record a Beatles songs. With that in mind, use the following rules: The artist/group must have released more than one album (but can include singles). This is to ensure that he/she/they had the space to record a cover. The song must be officially released (no bootlegs or unofficial releases). The cover can be a song that The Beatles themselves covered, as long as it was released after The Beatles version (so Post-Beatles versions of songs like "Twist And Shout" are eligible). This includes portions of Beatles songs included in a medley. A song written by members of The Beatles are only eligible if The Beatles themselves recorded it (so "I Don't Want To See You Again" by Peter & Gordon (written by Paul McCartney) is not eligible. Parodies don't count. To start off, I will mention Gilbert O'Sullivan. As far as I know, with one exception (a duet) he has only released songs written by himself.
