Hard Out Here sees her joining a brace of backing dancers to skewer the entrenched sexism of the music industry. The audience packed into Glasgow Green hardly care for such political points - they're just looking for fun. And Allen produces the goods in spades with tongue lasciviously in cheek.
Her new album, Sheezus, gets a thorough airing with Hard Out Here, URL Badman and Our Time. The slight Air Balloon risked sounding inconsequential on such a large platform but Allen injects it with so much fun that it rings out across the park. Fitting in a change of skirt between tracks, Allen carried the crowd along with her on a swell of positivity, not least during Smile. Her voice occasionally struggles with pitch and tone but was more powerful and commanding than might be expected from her studio recordings. It's Not Fair, with its jaunty country-style backing and a slew of images of naked beefcakes has the crowd bouncing.
With a deep tan and sparkling gold top, Allen is a vibrant affair, catching the last rays of the late afternoon sun.
