It read: "We are devastated to share the news that Alan has passed away peacefully surrounded by family.
"He was an extraordinary man with an extraordinary heart.
"He brought so much love and kindness to everyone he met, and he leaves a huge hole in our family.
"He would humbly say he was 'just a plumber from Edinburgh who got lucky'. However, we are the lucky ones; the ones that were lucky enough to have Alan as part of our lives.
"We'd like to thank everyone for the love and support that they have provided so far."
The Bay City Rollers were one of the biggest teen bands of the 1970s, selling over 100 million records with hits including Bye Bye Baby and Shang-a-Lang.
The band's frontman Les McKeown was among those to pay tribute to Alan Longmuir, writing:
"RIP Alan Longmuir... the original Bay City Roller."
