Blimey! Thanks, Danny. I never would have worked out that one. I still think it should be side (sing.), though, as only right is being changed to left. Surely we'd need an additional l to r change to make the plural valid? Anyway, on a separate issue, I probably wouldn't have got it at all if Loach hadn't been an answer a couple of weeks ago, too. Might be worth swotting up on the cast list of I, Daniel Blake given the setter's penchant for clues along the lines of 'actress'.
