"Benefit" is the third studio album by the British rock band Jethro Tull, released in April 1970. It was the first Tull album to include pianist and organist John Evan (though he was not yet considered a permanent member of the group) and the last to include bass guitarist Glenn Cornick (who was fired from the band upon completion of touring for the album). It was recorded at Morgan Studios, the same studio where the band recorded its previous album "Stand Up". The album incorporated studio techniques such as reverse recording (flute and piano tracks on "With You There to Help Me"), and manipulating the tape speed (guitar on "Play in Time"). The UK and the US release are different. The US version of "Teacher" (with flute) was placed on side two of the album, and the track "Alive and Well and Living In" was excluded. In the UK, "Teacher" was the B-side of the non-album single "The Witch's Promise", and was without a flute. In 2013, the Collector's Edition of Benefit was released. It contains bonus tracks mixed by Steven Wilson, a disc with mono and stereo mixes of rare and previously unreleased versions of tracks and singles and an audio-only DVD that includes a surround sound mix of the original album. The Collector's Edition also includes a booklet featuring an 8,000-word essay written by Martin Webb, as well as interviews with band members and a selection of photos, some previously unseen. For the 50th anniversary of the album, an enhanced edition was released in 20
