A DJ appeared to take a dig at Israel Folau by playing YMCA on Saturday at Christchurch's AMI Stadium.

The Warratahs fullback was the centre of controversy after saying in April God's plan for gay people was "HELL... Unless they repent of their sins and turn to God".

The Village People released the YMCA in 1978 as a reference to gay culture, specifically celebrating the Young Men's Christian Association's reputation as a place for young men to meet and, potentially, hook up.

"Young man, there's no need to feel down. I said, young man, pick yourself off the ground," thundered across AMI Stadium.

"It's fun to stay at the YMCA. They have everything for you men to enjoy. You can hang out with all the boys."

Folau suffered no consequences for his comments, avoiding sanctions. But he did offer to quit if Rugby Australia chief executive Raelene Castle felt he was harming the sport, or that his position was untenable.

Some New Zealand sports players and celebrities denounced his comments. High profile rugby players waded into the debate, a territory rarely ventured into in the past.

Among those to volley against Folau were Chiefs halfback and one-test All Black Brad Weber, Hurricanes halfback and All Black TJ Perenara, Kiwi director (and New Zealander of the Year) Taika Waititi, and TVNZ's Breakfast presenter Matt McLean.

Now, whoever was playing the music at AMI Stadium on Saturday can be added to the list of challengers after cuing up YMCA for the fulltime festivities. Whether it was intentional or not, the song's meaning was not lost on the crowd.

Crusaders CEO Hamish Riach said fans could expect to hear the song again.

"We've worked really hard on our fan experience this year at our games, and the music is a big part of that," Riach said.

"The song was merely played as a way to get the crowd involved in what was an exciting and close-fought game. We were delighted with the crowd response to it and for that reason we are likely to use it again."

THE MATCH

At half-time, the Waratahs were winning 29-12, but the Crusaders' pushed back to claim a 31-29 win at full-time, denying the Warratahs the chance to score again.

It was the biggest comeback in Super Rugby history, and Australia's 39th consecutive loss against a New Zealand Super Rugby team.

Things had been looking good for the Waratahs to end their 38-match losing streak, but then they lost two players to yellow cards and the Crusaders proceeded to score 31 successive points to steal the win.
