John Reid, leader of the Nightcrawlers and composer of legends such as Tina Turner, Rod Stewart and Kelly Clarkson, dies "suddenly."

Anyone who visited a pub or club in the 1990s must have heard, and inevitably danced, to the song "Push the Feeling On." What almost no one knows is that this dance music anthem was created and performed by John Reid and his group Nightcrawlers . The Scotsman died this Tuesday at the age of 61 "suddenly," according to TFX singer Mary Kian , who was engaged to Reid for nine years.

A versatile artist, after the success of Nightcrawlers, he continued his career as a DJ and composer. In the latter capacity, he achieved great success and wrote songs for music icons. He composed, among many others, "When the Heartache Is Over" for Tina Turner and "A Moment Like This" for Kelly Clarkson and Leona Lewis. He also worked with artists such as Simon Cowell, Rod Stewart , and Eternal.

Mary Kiani has mourned the death of her former partner. "I just found out this morning that my first love, John Reid, died suddenly. We met in Glasgow, but fell in love in London. He was recording his album with Roy Hay (of Culture Club) for his new band, This Way Up. Danusia Danoosha, Zaremba, and I were on tour, and every night we would meet at the Columbian Hotel," she recalled.

"We separated nine years later. Last year, I contacted him. I told him I'd love to say hello again before either of us passed away. I saw him last year in Glasgow. Rest in peace, John. Love, Bubbs. Hugs and kisses," she added.

Singer Chris Judge , a friend of Reid's, also wanted to say goodbye. "I remember him touring all over the country... back in the boy band days, he was always a really nice guy, very encouraging and supportive of all the new bands... He had a lot of success as a songwriter, but it was his voice I loved; he was an incredible and highly respected singer," he wrote on social media.
