The band were supported by a grant from The Prince's Trust when they first formed in 1994. "We bought our first PA system with [the money] and still have it now, it comes out for family weddings," drummer Dominic Howard told.
"I guess you could say we owe Prince Charles £250."
Muse were speaking after last night's Brit Awards, where they lost out to Coldplay for Best Live Act and Mumford & Sons for Best British Group. However, that didn't dampen their spectacular performance opening the awards bash where they performed "Supremacy" with a 75-piece orchestra flanked with pyrotechnics.
Earlier, Muse revealed that they were traveling to the Brits on the London Underground (via NME). The band tweeted a string of pictures of them on the Jubilee Line on their way to the O2 Arena in Greenwich.
"Heading to Brits by tube, beat the traffic!" they wrote, adding "Jubilee all the way!" Back in 2011, Rihanna was spotted on the Jubilee Line en route to her gig at Greenwich's O2 Arena.
Muse will play four massive UK SHOWS in the summer with Dizzee Rascal AS support.
Muse will play:
05/22 - Coventry - Ricoh Arena 05/25 - London - Emirates Stadium 05/26 - London - Emirates Stadium 06/01 - Manchester - Etihad Stadium
