Love is in the air ... Peter McKenna loves the Marngrook Footy Show and Grant Hansen loves Peter McKenna

What an absolutely sensational guest Collingwood legend Peter McKenna was on the Marngrook Footy Show, which airs around Australia on Foxtel's NITV channel (channel 180) on Thursday night's from 7.30 to 9.30.

The goalkicking machine was thrilled with his special guest appearance.

"I'm honoured to be on the best football program in Australia," he said.

"Everyone knows that. (It's) the real football show.

"All my mates watch it."

Host Grant Hansen couldn't contain his delight to have McKenna on his show.

Even though Grant barracked for the Bulldogs, he loved watching McKenna strut his stuff in front of the big sticks.

"When I was a kid, you were my idol," he said.

"I barracked for Peter McKenna."

Grant added: "You were bigger than The Beatles."

McKenna replied: "I had the same hair cut."

McKenna recalled supporting Essendon as a young boy.

"I was a mad-Essendon supporter as a kid," he said.

"My great hero was ... I didn't see him play, but he was my hero - (full forward) John Coleman, the famous John Coleman as a real little kid."

He also mentioned centre half-forward Ken Fraser and "rough and tough" centre half-back "Bluey" Shelton as other favourites.

McKenna answered honestly when quizzed about Collingwood's infamous fade-out after half-time in the 1970 grand final against Carlton.

The Magpies lost by 10 points after leading by 44 points at half-time.

"It's a shocking feeling," he said.

"That was the one that got away. No excuses. We had our chances and blew it."

McKenna retains a love for the Magpies and the game itself, but he does admit to being frustrated by one thing in particular.

"I go to most Collingwood home games," he said.

"I love the game. The pace is unbelievable

"But I don't like the 50 metre penalties being paid. It drives me nuts."

McKenna enjoyed his time on the Marngrook Footy Show so much, he'll return for another special guest appearance on the Marngrook Footy Show's star-studded Grand Final edition.
