Sharing kisses with eager fans has almost become a signature component of Sam Hui concerts.
For years, the 65-year-old veteran singer-songwriter has been known to freely plant kisses on his adoring fans - and he lets them do the same to him.
So Singapore fans can expect the same treatment at his concert here on Saturday, he says in a telephone interview.
But does his wife ever get jealous over such actions?
"She's used to seeing it, so she doesn't get jealous," he says breezily in Cantonese from his home in Hong Kong.
"I just love my fans too much, so I want to show them my appreciation. And they see me more as their big brother than anything else. I'm just grateful for their support."
Hui, who has been married to Filipino-American Rebecca Fleming for 42 years, adds that jealousy is not an issue as the couple "trust each other and admire each other".
"We also work on our romance. We travel together and we have candlelight dinners," he says with a chuckle.
He does not say whether his wife will be attending his Singapore concert, but reveals that his two sons, Ryan and Scott, will be on stage to sing a few tunes with him.
His older son Ryan, 37, also designed the posters used to promote the tour What A Wonderful World, while his film-maker son Scott, 35, helmed the concert's promotional video.
One concert guest star who will be greatly missed at the upcoming show is Hui's late older brother Ricky, who died of a heart attack in 2011.
Ricky and Hui were known to have been very close, with Ricky being the go-to guest star for many of Hui's concerts over the years.
Mention his brother's name and Hui sounds incredibly sentimental. "I miss him a lot and I think about him all the time. I often look at his old photographs and think about him."
