Anthony Yorfido desperately wanted to see Aerosmith frontman Steven Tyler’s solo concert in Niagara Falls last week, but couldn’t get a ticket.

But thanks to a chance encounter, the 23-year-old, from Welland, Ont., didn't miss a thing.

Yorfido, who has Down syndrome, had his dream come true when he spotted Tyler pulling up in a limo during a routine visit to a medical supply store with his mother, Diane, on Thursday.

"I saw a big, big … limo," Yorfido told CTV News.

"When I walked in, I saw the ponytail and I said, 'Oh my god, that's Steven Tyler.' I went crazy."

Yorfido said he managed to compose himself before introducing himself to the rockstar.

"I just (stood) there for a second and I said, 'Steven Tyler?' He turned around, came to see me and gave me a big hug," he said.

After the two embraced, Yorfido mentioned how much he wanted to see him in concert, and how upset he was that he couldn’t get a ticket.

And Tyler was moved, telling Yorfido that if he wanted to attend the show he would "make it happen."

Yorfido ended up getting backstage passes to the sold-out show, and he was brought out to play maracas when Tyler performed Aerosmith’s hit song "Sweet Emotion."

Those are four minutes that he'll likely never forget.

"The crowd went nuts … the people went crazy for me," said Yorfido.
