Muse helped to raised awareness of dementia (December 18) at a concert in Belgium.
The band introduced a charity gig by welcoming a choir of people with the condition and their families to perform a version of their single "Follow Me" scroll down to listen to it.
At the benefit, organised by national radio station Studio Brussel, drummer Dom Howard bought on the choir - called De Betties - by saying:
"We are very proud to have this great choir with us tonight who are going to play a song and they are raising awareness for dementia".
Muse later performed last night in Antwerp as part of their current world tour, which has been described by the band's frontman Matt Bellamy as their "best tour so far", NME notes.
The band are set to return to the UK next summer for a four-date stadium tour. They kick off the shows at Coventry's Ricoh Arena on May 22, 2013, before playing a pair of dates at London's Emirates Stadium on May 25 and 26, and wrapping up at Manchester's Etihad Stadium on June 1.
Also, the trio announced that they are to headline Rock In Rio next September. Muse will be supported at the bash in Rio de Janeiro on September 14, 2013 by Alice In Chains.
