It is rumored in 2003 that White was featured on Electric Six's song "Danger! High Voltage." Initially both he and the Electric Six denied this, and the vocal work was credited officially to the unknown John S O'Leary. However, a recent radio interview with Tim Shaw on Kerrang! 105.2 in the UK had Electric Six lead singer Dick Valentine talking openly about White singing on this song as well as speculating on the amount of money he was paid ($60,000).
White was the subject of The Flaming Lips's song Thank You Jack White (For The Fiber-Optic Jesus That You Gave Me) released on their 2003 Fight Test EP.
White, following his arrest in 2003On December 13, 2003, White was involved in an altercation at The Magic Stick, a Detroit club, with Jason Stollsteimer, lead singer of the Von Bondies. He was charged with misdemeanor aggravated assault. He pleaded guilty, was fined $500 plus court costs, and was sentenced to take anger management courses.
White played bass on the song "Go It Alone" from the Beck album Guero. Beck, a friend of White's, appeared in the White Stripes video for "The Hardest Button to Button."
White made a surprise appearance with Bob Dylan during Dylan's performance in Detroit on March 17, 2004 during the second encore, performing the White Stripes song "Ball and Biscuit."
White has referred to The Stooges' 1970 album Fun House as "the greatest rock 'n' roll record ever made." As a result, he was invited by Rhino Records to contribute liner notes to the 2005 deluxe reissue of the album.
On November 7, 2005, it was widely reported that Jack White had changed his name to "Three Quid" (quid is British slang for pound sterling). However, most reports (e.g. Undercover.com,NME.com, and MTV.com) indicated that this would only last until the end of the tour. When asked about this in a UK radio interview, he claimed that "it's all a money thing....it's all about money."
In April 2006, a long-rumored and extremely low-profile Coca-Cola commercial debuted during the MTV Australia Video Music Awards, featuring the original song "Love is the Truth" that White wrote exclusively for Coke. As White generally advocates "brand-free music," it was a departure from this stance. In defense of his involvement, White stated, "I've been offered the opportunity to write a song in a way which interests me as a songwriter. I certainly wouldn't want a song that I'd already written to be used on a commercial. That seems strange." However, according to InTheNews.co.uk, the ad was only played once in the UK, late at night on Channel 4, and was available for only a short time at the Coke website.
