(CNN) Americana singer and songwriter David Olney, whose music was recorded by Linda Ronstadt, Steve Young, Emmylou Harris and others, died of an apparent heart attack while performing on stage in Florida Saturday, according to a statement on his website. He was 71.

Olney stopped in the middle of a song and paused, said "I'm sorry," and "put his chin to his chest," said fellow singer-songwriter Scott Miller, who was performing with Olney at the 30A Songwriters Festival in Santa Rosa Beach.

"He never dropped his guitar or fell (off) his stool," Miller wrote on Facebook . "It was as easy and gentle as he was."

Amy Rigby, who also was on stage with Olney, also wrote a powerful Facebook post

"He was very still, sitting upright with his guitar on, wearing the coolest hat and a beautiful rust suede jacket ... I just want the picture to be as graceful and dignified as it was, because it at first looked like he was just taking a moment," Rigby said, adding, "We all lost someone important last night."
