Downton Abbey's Michelle Dockery and Michael Fox make debut as a folk duo

The pair - billed as Michael and Michelle - wowed 300 fans at a sell-out

show at one of London's trendiest underground music venues.

Michael - footman Andrew Parker in the show - and Lady

Mary Crawley star Michelle discovered their mutual love of folk music while filming.

A casual off-set jam led to practice sessions before

the pals took to a recording studio in Los

Angeles last year to record EP The Watching Silence.

After its recent release, the pair took to the stage of Omeara in London Bridge on Monday night.

Michelle, 40, looked worlds apart from her Downton character as she rocked the mic, while Michael, 33, sang and accompanied on acoustic guitar.
