Dan McCafferty, the power-voiced founding frontman of Scottish rock band Nazareth,

who sang lead on its Top 10 U.S. hit “Love Hurts,”

FM staple “Hair of the Dog” and five Top 15 UK hits, died Tuesday. He was 76.

His longtime bandmate, bassist Pete Agnew, revealed the news on social media.

“This is the saddest announcement I ever had to make,”

he wrote on the group’s Facebook page.

“Maryann and the family have lost a wonderful loving husband and father,

I have lost my best friend and the world has lost one of the greatest singers of all time.”

McCafferty co-founded Nazareth in 1968 with Agnew, guitarist Manny Charlton

drummer Darrell Sweet and retired from touring in 2013 — after 45 years

due to the effects of COPD. He sang on all of its nearly two dozen albums until 2014.
