KEITH McIvor, one half of the legendary Glasgow DJ duo Optimo, has passed away at the age of 57.
Keith, also known as DJ Twitch, died just three months after sharing he had been diagnosed with an untreatable brain tumour.
He was admitted to The Prince and Princess of Wales Hospice in Glasgow in August.

On Saturday morning, Optimo co-founder Jonnie Wilkes announced that Keith had passed away on Friday afternoon.
He said: “It’s with immense sadness that I’m writing to tell you Keith passed away peacefully yesterday at 2.06pm at The Prince and Princess of Wales Hospice in Glasgow.
"In a 28-year partnership, he changed my life immeasurably and together we took our work in directions and to places few people are lucky enough to explore.”
Wilkes added: "I am forever grateful for everything he bestowed on me, both as a partner in music and as a friend. Keith’s intensity and passion for life, for music, for creativity and for positive change simply never let up. He was formidable.
"His belief in people and the idea that standing together, that our collective strength is powerful, was unwavering. I loved him for that.
"My thoughts are with Keith’s family and friends. Thank you to them and the extended group who have tirelessly supported Keith and each other in the last few months. Thank you to the staff at The Hospice who made this last while as good as it possibly could be.
"Keith left us far too soon. He will go now to travel those space-ways but I know his energy remains in every one of us who had the privilege of knowing him. I love you forever, Keith."
Alongside Wilkes, Keith founded one of Glasgow's most famous club nights – Optimo Espacio – held at Sub Club on Jamaica Street from 1997 until 2010.
A fundraiser gig was held in July to help raise money for Keith's treatment and for local food banks.
