On May 17, 2006, Panic! at the Disco announced that original bassist Brent Wilson had left the band, "posting a statement that was both diplomatic and entirely inscrutable […] yet to mention any reason why Wilson is leaving Panic," according to MTV News. He was replaced in the band by Jon Walker. In June, Wilson asserted to MTV News that he was kicked out of the band via a phone call. "It was done as a phone call and the only person who spoke was Spencer. Apparently, Brendon and Ryan were on the speakerphone too, but they didn't say a word. They never even said they were sorry," explained Wilson. Smith wrote a lengthy e-mail back to James Montgomery of MTV News, stating, in part, "We made the decision based on Brent's lack of responsibility and the fact that he wasn't progressing musically with the band," and revealed that Wilson did not write nor play any bass present on "Fever": Instead, Urie recorded these parts. Wilson demanded a cut in royalties, and threatened to take his former band to court.
