Frank Sinatra collapsed face down on stage late Sunday night while singing My Way during a concert in Richmond, Va. But the 78-year-old singer recovered quickly and waved feebly to the cheering crowd as he was wheeled off stage and taken to a hospital. Sinatra spokeswoman Susan Reynolds said he "became overheated and passed out for a few moments. Mr. Sinatra's vital signs are stable. He is talking and is alert." A supervising doctor who would not give his name said Sinatra would be held overnight for observation. The hospital did not immediately release Sinatra's condition. Sinatra collapsed toward the end of his second sold-out show at the city-owned Richmond Mosque auditorium. Sinatra, who has recorded more than 100 albums and made 58 films, received a lifetime achievement award last week at the Grammys.
