BOSTON (CBS) – Singer Joey McIntyre lent his vocals to the Boston Pops on Tuesday.

For the second year in a row, the New Kids on the Block front man teamed up with the Pops to sing for the kids at Children’s Hospital Boston.

As a father of three, McIntyre says seeing the kids’ smiles is one reason he’s back this year.

He also admits a bit of nostalgia brought him back.

“Number one, I’m from Boston and I came here as a kid; had a broken leg when I came in here and they popped it back into position… and I screamed like a little monkey,” he said.
