McCartney Is No. 1

Paul McCartney has done it again - he's topped the classical charts in both the U.S. and the U.K. with his new symphony "Standing Stone."

McCartney took a break from making rock music recently to pen his second symphonic work, which hit No. 1 on the charts on both sides of the Atlantic. "Standing Stone" was introduced by the London Symphony Orchestra last week.

"I'm very pleased that so many people seem to like 'Standing Stone.' It's exciting for me to work in a different musical field," McCartney told Reuters on Monday. "I really see no barriers in music, although I think too many people do."
