Cyndi Lauper’s return to Glastonbury was beset by sound problems that left the audience struggling to hear her vocals.
For the first few songs, the star’s voice was drowned out by rumbling bass. When fans could hear, she seemed to be struggling to find her pitch and timing -particularly on a wayward version of Rocking Chair.
The issues appeared to have been resolved by the time she got to the power ballad I Drove All Night, with her voice suddenly resonant and powerful in the mid-afternoon sun.
But she faltered again on Time After Time, with the delivery on one of her earliest hits from 1984 lagging behind the band - suggesting she was having trouble with her in-ear monitors.
At times, the singer appeared to be in dispute with members of the production team by the side of the stage.
