The two have found that they could be a very funny couple onstage in front of thousands of people.Like her and her screen son, Seth Rogen, in The Guilt Trip (out Wednesday), Streisand and Gould showed some serious bantering chemistry that built until the final night of the 10-city tour at The Hollywood Bowl. During that show, the two had the crowd in stitches.
"As I got more comfortable, I found I could respond to anything," says Gould, 45. "The last night, it was pretty funny and it wasn't planned. This is a first."
Gould (Streisand's only son from actor Elliott Gould, to whom she was married from 1963 to 1971) says that this is not how the two interact behind the scenes: "Stage is not life."
Streisand, 70, made Gould a regular part of her mostly large-venue tour, with the two singing How Deep Is the Ocean each night. But Gould did not want his role announced, because he had never sung before so many people.
"I did not know if my knees would buckle. I did not know if I could do it," he says. "I didn't want to set this up. I learned I could do it. It's been weeks afterward, and I cannot believe I sang in front of thousands of people at the Hollywood Bowl. I don't know who that person is."
Gould has acted on stage and in films, including parts in 1989'sSay Anything ... and the Streisand-directed The Prince of Tides. But recently, he has turned to music with the October release of his debut five-song EP, Jason Gould, which includes How Deep Is the Ocean.
There is discussion of re-recording Ocean with his mother for a duets album she is working on and of continuing the tour with European stops.
Streisand says her relationship with Gould is very different from the relationship she portrays with Rogen on-screen. But there are different struggles in every parental relationship, she says.
"Kids rebel against their parents no matter what line of work they are in," she says. "That dynamic is always complicated, whether the mother loves too much or is overbearing or is distant."
Gould says there is common ground between his world-famous mother and Joyce, the middle-class housewife she plays in The Guilt Trip.
"My mother is a mensch," Gould says. "She's complex, probably much more than Joyce. But there's a lot of soul and heart. She's a sensitive person and a generous soul. There's a lot of love in there."
