On Wednesday, the 70-year-old singer posted a photo to Instagram of what appeared to be his mom's coffin along with an emotional message.
"Dear Mum, Today’s funeral was perfect," he writes. "Having the service in the family chapel and attended by your brother and sister brought us all comfort. Having the service where Nan lived out her final days brought you and your mother back together again."
John apparently attended a private funeral service as he notes in the letter that there will be another service for Farebrother on Thursday. "Tomorrow your friends will gather separately to say their good byes. I’ve chosen all the music so everything will be just right," he continues. "Thank-you for bringing me into the world and for all that you have done for me. Love, Elton."
On Dec. 4, John tweeted that his mother had died at 92. "So sad to say that my mother passed away this morning. I only saw her last Monday and I am in shock," he wrote. "Travel safe Mum. Thank you for everything. I will miss you so much. Love, Elton."
John also posted a photo of himself and Farebrother from June 2003, when they attended the Fifth Annual White Tie and Tiara Ball to benefit his foundation.
So sad to say that my mother passed away this morning. I only saw her last Monday and I am in shock. Travel safe Mum. Thank you for everything. I will miss you so much.
While there were reports that John and his mom had fallen out of touch in recent years, the "Rocket Man" musician did wish her a Happy Mother's Day in May, writing: "Dear Mum, Happy Mother's Day! So happy we are back in touch."
