Elton John Reunites With His Grammar School Classmates

— -- Elton John has not forgotten where he came from.

The 68-year-old, Grammy-winning artist recently reunited with his classmates from London's Pinner County Grammar School, which he attended until he was 17.

"Lunch at home with dear old school friends," he wrote alongside a photo of him and his schoolmates. "Many of whom I haven't seen for 50 years! It was as if we never left school. So much laughter and so many wonderful memories. #ShareTheLove #PinnerCountyGrammarSchool #Classof58"

While the whole group hasn't been together for a while, John has kept in touch with some of his Pinner classmates.

He posted a photo with one of them, writing, "My oldest pal Keith Francis. A wonderful, loyal friend for 57 years and still counting! He flew all the way from Australia for our class reunion. Love you so much. #ShareTheLove #PinnerCountyGrammarSchool #Classof58"

John has been very busy these days. In addition to preparing to go on tour, the British musician testified earlier this month in front of the U.S. Senate Appropriations Committee about his AIDS foundation's efforts.

"This is the most powerful legislative body in the world," John said. "This Congress indeed has the power to end AIDS. I am asking you to use that power, to seize this window of opportunity, to change the course of history."
