'Tis the season for Glen Hansard to be playing short-notice gigs in Dublin, but several days before his annual 'Christmas Eve on Grafton Street' shindig, Glen Hansard has turned up at a different Dublin venue to raise awareness for a good cause.

Hansard has been an advocate for the 'Home Sweet Home' campaign which saw citizens reclaiming empty building Apollo House in on Poolbeg Street to house some of the many homeless people on the city streets.

After Damien Dempsey's set at the site last week, Hansard turned up to play a few tunes - along with the likes of Hozier, Kodaline and Christy Dignam and Joe Jewell of Aslan - as a huge crowd gathered there this afternoon.
