Daniel David Kirwan (13 May 1950 – 8 June 2018) was a British musician whose greatest success came with his role as guitarist, singer and songwriter with the blues rock band Fleetwood Mac between 1968 and 1972. He released three albums as a solo artist from 1975 to 1979, recorded albums with Otis Spann, Chris Youlden, and Tramp, and worked with his former Fleetwood Mac colleagues Jeremy Spencer and Christine McVie on some of their solo projects.
He is also known as Daniel David Kirwan.
Kirwan died in London on 8 June 2018. An obituary in The New York Times quoted Kirwan's former wife, Clare Morris, as saying that he had died in his sleep after contracting pneumonia earlier in the year and never fully recovering from it.
In a statement posted on Facebook, Mick Fleetwood said, "Danny's true legacy will forever live on in the music he wrote and played so beautifully as a part of the foundation of Fleetwood Mac that has now endured for over fifty years. Thank you, Danny Kirwan. You will forever be missed."
Fleetwood had previously said in an interview, "I cared for Danny a lot and I care for his legacy. Danny was a quantum leap ahead of us creatively. He was a hugely important part of the band."
