The Overtones hitmaker’s death aged 36 was confirmed by his bandmates on Twitter yesterday, two years after he was diagnosed with skin cancer.
The tragic tweet, shared with their 55,000 followers, read: “It is with the greatest sadness that we have to announce that our dear friend and brother Timmy has passed away.
“We know this news will be as heartbreaking for you all as it is for us. We appreciate your love and support at this difficult time. Mike, Darren, Mark and Lachie.”
Timmy had returned to his hometown of Cork last month to celebrate his mother’s birthday and St Patrick’s Day.
The talented singer shared numerous pictures and videos on his Instagram page, as he gushed about his “family” and “good times”.
Posting on March 17, Timmy was seen waving an Irish flag while watching a parade, which saw numerous children dressed up for the special occasion.
Beaming at the camera while wrapped up in a chunky scarf, he was joined by a female companion for the celebration.
Timmy captioned it: “Happy St Patrick’s day love from Cork x #happystpatricksday #family #blarney #cork #theovertones.”
The previous day, he had seemingly been in a nostalgic mood as he looked through mementoes from the start of his career.
“Mam found some bits and pieces before I left home to follow my dreams in London,”(sic) Timmy wrote.
He continued: “Happy times looking back with her at where it all began. #memorylane #blastfromthepast #dreams #cork #love #goodtimes #theovertones.”
Timmy had also made sure to wish the woman in question all the best, sharing a photo of her with a dessert complete with candle.
“Happy birthday Mammy !!! X #Mammy #family,” he stated, before branding her his “wonder woman.”
Timmy also poignantly stated: “Here’s to many more. Fizz and good times to be had @oystertavern #mammysbirthday #family #cork #goodtimes.”
He had also informed on March 11: “Mammy I’m on the way home to cork for a few days. #mothersday #cork #theovertones #mammy @aerlingus.”
It comes after The Overtones were instantly inundated with comments from mourning fans, with This Morning host Phillip Schofield writing: “I’m so terribly sorry to hear this and sending lots go love to you all particularly Timmy’s family and his many friends.”
“I just can’t believe it,” another said. “My heart breaks for you and his family. In total shock. Sleep tight Timmy.”
A third commented: “I’m absolutely heartbroken to hear this. Timmy was one of the nicest people I’ve ever met. He was always so amazing with fans.”
The band, comprised of Timmy, Mark Franks, Mike Crawshaw, Lachie Champman and Darren Everest, are a platinum-selling doo-wop vocal harmony group.
A representative for The Overtones told Express.co.uk that there was no information as of yet about the circumstances surrounding his death.
