Kings of Leon cancel rest of U.S. tour after 'exhausted' Caleb Followill abandons bandmates at Dallas concert

A statement released by the rock band claims the lead singer Caleb Followill, who recently married Victoria's Secret model Lily Aldridge, is suffering from 'exhaustion'.

It comes four days after he angered fans in Dallas by abruptly walking out mid-concert because it was 'too hot.'

A string of tweet by the band after Friday night's disastrous performance hinted at mounting disharmony between the group.

The first thing that strikes you about Kings of Leon’s fifth album, Come Around Sundown, is the sheer musical diversity of its songs, which touch on everything from gospel (spiritual, up-tempo rocker "Radioactive"), angular post-punk ("The Immortals," "Pony Up"), bonafide country ("Back Down South"), and even ’50s-style doo-wop ("Mary"). The album’s huge range proves that Kings of Leon haven’t lost the restless, experimental nature that has made them such an exciting band to watch. http://KINGSOFLEON.jonesbeach.com

That Caleb, Nathan, Jared, and Matthew Followill continue to follow their own muse and refuse to play it safe is especially impressive coming as they are on the heels of Kings of Leon’s most successful album to date: 2008’s Only By The Night, which catapulted the band into the mainstream. The multi-platinum-selling album debuted in the Top 5 on the Billboard Top 200 chart, hit No. 1 in five countries, sold more than 6.5 million copies worldwide, and earned Kings of Leon four Grammy Awards, including wins for their Modern Rock radio multi-week No. 1’s "Sex on Fire" and "Use Somebody" (which led to what drummer Nathan Followill describes as a "surreal and drunken" trip to the podium to collect an award for "Record of the Year" from Ringo Starr). The album’s success also led to the band’s gracing the covers of Spin and Rolling Stone, performances on Saturday Night Live and The Today Show’s summer concert series, a sold-out show at New York City’s Madison Square Garden, and headlining slots at Bonnaroo, Lollapalooza, and Austin City Limits festivals.
