A statement on his website says he died Wednesday.

The Los Angeles Times reports Edwards was hospitalized earlier this month in Denver after collapsing while on tour with Bonoff. He was airlifted to a hospital near his home in Santa Barbara where he died.

After the Stone Poneys disbanded after their 1967 breakthrough hit “Different Drum,” Edwards formed the folk-rock band Bryndle with singer-songwriter Wendy Waldman, Bonoff and Andrew Gold.

He also was a supporting guitarist and singer for Stevie Nicks, Don Henley, Brian Wilson, Art Garfunkel, Vince Gill and others.
