The 'Caps had a very special guest at training on Friday as Marcus Mumford, lead singer of English band Mumford & Sons, joined the Blue & White for a scrimmage before the band's show tonight at Holland Park in Surrey.

Check out the scenes from today's visit:

FUN FACT: Mumford, a native of London, England, is a staunch supporter of English club AFC Wimbledon where Whitecaps FC midfielder Nigel Reo-Coker began his career and played as captain.
