LONDON — U.S. pop singer Jimmy Osmond, who performed the chart-topping hit “Long-Haired Lover from Liverpool” as a child in 1972, has suffered a stroke and will take time away from the stage, a spokesperson for the singer said on Monday.

Osmond completed a performance of the Peter Pan pantomime on Dec. 27 at the Birmingham Hippodrome theater in central England before he was driven to hospital and diagnosed with a stroke, the representative said in a statement on the theatre’s website.

Osmond, now 55, was the youngest sibling in The Osmonds family troupe and became the youngest person to reach number one on Britain’s singles charts with the release of “Long-Haired Lover from Liverpool” when he was aged nine.

“He is grateful for all the well wishes and will be taking time out in the new year,” the spokesperson said.
