Concertgoer Trevor James tells ET that Meat Loaf's voice "was a little coarse and he walked slowly and with a limp," adding that the singer "seemed fine to me through the majority of the concert."
"He was in the middle of [singing] a line and kind of hunched, dropped the [mic] and fell. He then rolled through onto his back," James recounted. "I don't think many people thought it was part of the show and everyone just went silent and there was a lot of concern."
Other fans in attendance also reported that medics brought out a defibrillator, although this has not been confirmed by authorities.
James told ET that he didn't see them hook the singer up to the defibrillator, adding, "I saw one there but didn't see it used."
"Meat Loaf collapsed Thursday night due to severe dehydration near the end of his concert at the Northern Jubilee Auditorium in Edmonton, Alberta Canada," his rep told ET in a statement. "He was admitted to a nearby hospital to undergo routine tests. His vital signs are stable and normal — he's responsive and recovering well. He extends his heartfelt thanks for everyone's support and well wishes, and is expecting a speedy and full recovery."
Everyone in the building was forced to evacuate when fire trucks and ambulances arrived on the scene, CBCnews reported.
The incident comes days after Meat Loaf, who was born Michael Lee Aday, cancelled his June 13 show at the Southern Alberta Jubilee Auditorium in Calgary "due to illness." The singer had played a number of shows across eastern and central Canada since the beginning of May.
