Rod Stewart, who started his career in the '60s by singing on the streets -- known in England as busking -- did just that Monday when he joined street performer Henry Facey for an impromptu runthrough of “Handbags and Gladrags” in London’s Piccadilly Circus.
Afterward, Facey said, “I was pretty nervous before it happened as I saw him from the corner of my eye and recognized him instantly. When he came up to the mi,c he had his usual cheeky charming smile that actually put me slightly more at ease (if it wasn't already from the bum pinch as he made his way past me to the mic!). But when he started singing...the power of his voice and that distinctive beauty in his tone were outstanding, a real highlight of my career as a musician and still can't believe it actually happened. There are honestly no words to express how thankful I am for this experience."
