US rocker Meatloaf says the AFL are jerks, and he's vowed to convince other artists not to perform at the grand final.
The 64-year-old's grand final pre-match performance, as well as his high price tag, were widely criticised in the media.
He was reportedly paid in excess of $500,000, a figure he disputes.
But Meatloaf has blamed the AFL, saying they did not provide a live piano or enough time for a sound check and he could not hear the music in his earpiece.
"I'm sorry, they're jerks. I do not like them," he said of the AFL, News Ltd reports.
"And I'll tell you what, anybody that I hear announces that they're going to play for them I'm going to write to that particular artist a letter and tell them not to.
"And I hope the AFL hears this and I want this everywhere. Because I will go out of my way to tell any artist do not play for them."
The rocker said it was impossible to put on a good show in the allocated area.
The AFL declined to comment.
