And yesterday there was little sign of a glitzy celebrity lifestyle as he was laid to rest in a small village graveyard outside Brighton.
The family of the 58-year-old rock musician, who died in his sleep of a heart attack while on holiday in Spain on February 6, had decided to hold his funeral, not in Belfast where he was born, but near where he had made his home for the past 15 years and where his children reside.
Fr Martin Morgan, who conducted the service in St Margaret's Church, Rottingdean in East Sussex, described Moore as "the kind of musician who would play anywhere if someone lent him an amp".
He recounted how the world-famous rock guitarist had once performed in a local pub to raise funds for victims of the Haiti earthquake.
"They asked lot of people to play but Gary was the only one who turned up. He was someone who took the talent he was given and used it to touch the soul of others. I believe for this generosity, Gary is in heaven," Fr Morgan told mourners.
The father of four is survived by his children, Saoirse, Lily, Jack and Gus. His daughter Lily Rendle-Moore spoke of her father as "a man with rather colourful shirts, who possessed a childlike quality and was an inspiration to many and the kind of person you could never forget".
The musician's other daughter Saoirse chose a verse for the service, 'Guitar Poem', which was read by a family friend.
Son Jack, himself a guitarist, performed a flawless version of ' Danny Boy' on guitar, at which some mourners wept.
Many of the mourners who had travelled over from Ireland later gathered to celebrate Moore's life at a function in Brighton's Dome Room.
The family had requested that donations in memory of Gary be given to aid the work of the Teenage Cancer Trust and to help a special needs educational project.
