Paul McCartney has revealed he still suffers nerves -- when he plays small corporate and charity gigs.
The superstar (67) said festivals in front of tens of thousands of people are no problem but he struggles with more intimate shows.
"If it's at all kind of corporate you don't know who you've got in the audience. It can be people who really don't like rock and roll, and you're sitting there going 'Yeah, we're going to have a great time tonight' and they're just chatting to each other."
McCartney told DJ Geoff Lloyd he once almost even threw up before a Beatles gig.
"I don't get that kind of nervous, because if the tickets sell really well, you get an idea that these people really want to come and see you," he said.
