British actor and comic Steve Steen makes his improvisational comedy acts look effortless, breaking into song at a moment's notice and switching between euphoria and terror in a heartbeat.
If indeed improv comes easy to him now, he has earned it - the hard way.
In a telephone interview with Life! to promote his upcoming show here, the 58-year-old wryly recalls a live show abroad: "We once did a show in the Caribbean, in Barbados, which I'd never been to before.
In front of all these people from Barbados, I was suddenly asked to sing a reggae song.
"I had no choice but to do it."
With enough experience under his belt, he says he has learnt to deal with unfamiliar cultural references that might be thrown his way.
These skills will come in handy when he performs in Singapore this week as part of the cast of the hit British improv comedy series, Whose Line Is It Anyway? (1988-1998).
"You just have to kind of go with the flow. When somebody shouts out a place, and the audience starts laughing, you just know that it is the red-light district," says Steen, who started out as a theatre actor in 1972 in productions staged at playhouses and events such as the Edinburgh Fringe Festival and Arts Theatre London.
