Bass guitarist Alan, who was a founding member of the Bay City Rollers, died in hospital at the age of 70 earlier this month.
Today, mourners have gathered in Bannockburn, Scotland, to pay tribute to the late musician.
The service, which took place this morning, saw mourners turn out in their droves to honour the memory of the star.
Alan’s family and friends could be seen gathering for a procession at the church.
The star’s wife Eileen Rankin, who wed Alan back in 1998, was supported by loved ones as she said her goodbyes to her spouse.
A notice published in the Stirling Observer, read: “Peacefully, after a short illness, surrounded by his loving family, on Monday 2nd July, 2018 at F.V.R.H., Alan, aged 70 years, founder member of the Bay City Rollers.
“Much loved husband of Eileen, loving father, brother and grandfather.
“Funeral service will be held at Allan Church, Bannockburn on Thursday 12th July at 11am, thereafter to Bannockburn Cemetery for approximately 12 noon, to which all family and friends are respectfully invited.
“Family flowers only please.”
Fellow Bay City Rollers star Les McKeown, 62, confirmed the sad news earlier this month, in a post shared with his 8,453 Twitter followers.
Beside a photo of the star, the message read: “R.I.P. Alan Langmuir. Alan Langmuir, the original Bay City Roller.”
It continued: “Alan passed away at 06.00hrs today Monday 2nd of July surrounded by his family and friends.”
According to The Mirror, the Scottish musician had been admitted to a hospital in Cancun, Mexico, with an illness a month ago.
Shortly before Alan’s death, Liam Rudden, who directed the stage show I Ran With The Gang: The Story of Alan Langmuir, provided fans with a health update.
A post on his Facebook page read: “Alan has returned to Scotland and been admitted to hospital.
“He continues to be seriously ill and is receiving extensive medical interventions.”
The star shot to fame after forming the hit band with his brother Derek Longmuir, 67, as well as Les and guitarists Eric Faulkner, 64, and Stuart ‘Woody’ Wood, 61.
The Edinburgh-born musician married twice, first to Jan Langmuir – from 1985 until 1990 – with whom he had a son, Jame Jordan.
Following his divorce, Alan later married Eileen in 1998, whom he was with until he passed away.
The Bay City Rollers, who were best known for their smash hits Bye Bye Baby and Shan-A-Lang, performed a series of reunion concerts two years ago.
