Men perform YMCA in their Royal Mile flat in Edinburgh on Hogmanay A video of four men dancing in the windows of their Edinburgh flat on Hogmanay has gone viral. The revellers are performing YMCA at the windows of the Royal Mile apartment, while the lights go on and off in time with the music. The performance was filmed by a number of passers-by, including Maria McMillan who posted the video on her Facebook page. It has since attracted more than 2000 shares and 6000 likes online. The four men can be seen performing at the window while cheered on by a growing audience on the Royal Mile, with one man on the street joining in with the dancing. As they dance, lights in the flat are switched on and off in time with the music, which is being played loudly from the window. Spectators can be heard wondering how they managed to get the lights to flash in time, with one speculating "it's a posh flat, they must have an iPad set up."
