Bruce Springsteen celebrated his 63rd birthday onstage until nearly 2 a.m. Sunday, joined at the end by his hearty mom.

Adele Springsteen danced and sang background to "Twist and Shout," walking offstage with her son and his band at nearly 2 a.m. Her only concession to age was a pair of hastily made earplugs.

She watched as her son cut a giant birthday cake in the shape of a guitar, passing out pieces to some audience members.

His show in the open-air MetLife Stadium was delayed three hours Saturday by authorities because of a downpour and worries about lightning. Thousands of fans clustered on indoor ramps waiting for the rain to stop.

When it did, Springsteen and his E Street Band took the stage at 10:30 p.m. to the strains of Wilson Pickett's "In the Midnight Hour," a song they performed when the clock hit that mark. They also covered Creedence Clearwater Revival's "Who'll Stop the Rain," and it worked.
