- Jefferson Airplane - According to Jorma Kaukonen the name was coined by a friend as a satire of blues pseudonyms such as "Blind Lemon" Jefferson.
- Jethro Tull - Having trouble getting repeat bookings, the band took to changing their name frequently to continue playing the London club circuit. Band names were often supplied by their booking agents' staff, one of whom, a history enthusiast, eventually christened them "Jethro Tull" after the 18th-century agriculturist. The name stuck because they were using it the first time a club manager liked their show enough to invite them to return.
- Joy Division - In order to avoid confusion with the London punk band Warsaw Pakt, the band renamed themselves from Warsaw to Joy Division in late 1977, borrowing their new name from the prostitution wing of a Nazi concentration camp mentioned in the 1955 novel The House of Dolls.
