Denny Laine, co-founder of Wings with Paul McCartney, died Tuesday after battling lung disease, his wife Elizabeth Hines confirmed to Fox News Digital. He was 79.

The "Band on the Run" singer formed two of the biggest rock bands of all time, both with The Moody Blues and McCartney's Wings.

"My darling husband passed away peacefully early this morning. I was at his bedside, holding his hand as I played his favorite Christmas songs for him," she shared on social media. "He’s been singing Christmas songs the past few weeks and I continued to play Christmas songs while he’s been in ICU on a ventilator this past week.
