“Sliiiiiide to the left!” Never has a late night rendition of the Cha Cha Slide at Dundee’s Apex Hotel better summed up a Scottish Labour conference.

It came after a lively karaoke night hosted by the party’s youth wing on Saturday. Frank McAveety, the former Scottish executive minister who now leads the Labour group on Glasgow council, resisted a nomination to perform Napoleon XIV’s They’re Coming to Take Me Away, Ha-Haaa! But to the shock and bemusement of the crowd, he happily belted out Roy Orbison’s Penny Arcade, the anthem of Rangers FC.

Soon after bestie MPs Paul Sweeney and Danielle Rowley were up with Oasis’s Don’t Look Back in Anger. Perhaps it’s a good job Ken Livingstone is no longer a Labour member — he once cut a disc with Blur, after all.
