Beach balls, balloons and a pea-green lilo bounced around in the away end before kick-off but a little of the air has gone out of Nottingham Forest's quest for automatic promotion after they crashed to defeat at Luton.
Steve Cooper's team lost in the Championship for the first time since January, a run of five wins in a row brought to an abrupt end at Kenilworth Road, where Kai Naismith scored the only goal from the penalty spot.
It was intense and bad-tempered at times but victory keeps Luton on track for an unlikely place in the play-offs.
