The vegetarian singer was midway through 'Some Girls Are Bigger Than Others' when he left the stage because of the aromas from nearby burger stalls, reports NME.
"I can smell burning flesh and I hope to God it's human," he said. Returning to the stage, he explained: "The smell of burning animals is making me sick. I just couldn't bear it."
Morrissey was reportedly able to finish his set, which included his latest single 'I'm Throwing My Arms Around Paris'.
