"Hymn 43" is a song by British progressive rock group Jethro Tull.

[2] Songwriter Ian Anderson described the song as "a blues for Jesus, about the gory, glory seekers who use his name as an excuse for a lot of unsavoury things.

'"[3] Sean Murphy of PopMatters wrote that, "For “Hymn 43” Anderson sets his sights on the US and in quick order sets about decimating the hypocrisy and myth-making of religion and the new religion, entertainment.

It is composed in the key of D major with Anderson's vocal range spanning from G4 to Eb6.

[5] Classic Rock History critic Skip Anderson ranked "Hymn 43" as Jethro Tull's 2nd best song, behind only "Thick as a Brick" and ahead of the more popular songs on Aqualung, "Aqualung" and "Locomotive Breath".
