Did you know this ?

Bono has admitted he suffers from severe stage fright - despite the fact he’s been playing to packed stadiums for 25 years.

The U2 frontman says he still feels "nervous" and "sick" when he wakes up on the morning of a gig, even after quarter of a century.

"The morning before a show I get nervous. I can wake up with a sick feeling," he told Harper’s Bazaar.

The 46-year-old Irish star also worries he might let the crowd down by giving a less than perfect vocal performance.

"I have to hit very high notes and if you hit them wrong you can put your throat out," he said.

"So there’s a ‘Will I? Won’t I?’ aspect to it.

"It used to worry me sick. That sense of, how could I meet the levels of anticipation?

"If you’re a rock star and need 25,000 people telling you they love you, obviously you must be a very insecure person," he joked.
