Bruce Williamson, a former lead singer for the R&B group The Temptations, has died, according to a Facebook post from his son. He was 49.

“There’s no words in the world that can express how I feel right now,” Williamson’s son wrote in a post Monday morning. “I love you Daddy thank you for being awesome thank you for being loving thank you for being Who You Are.”

Williamson reportedly joined the band in 2007, replacing the departing tenor G.C. Cameron, and left in 2015.

The lineup of The Temptations has changed frequently since the original group formed nearly 60 years ago. The act remains best known for its string of 1960s hits, including “My Girl” (1964) and “Ain’t Too Proud to Beg” (1966).

The New York Times, reviewing a seven-night Broadway production featuring The Temptations in 2014, called Williamson “a find: a large man who’s light on his feet and, even more important, full-throated with gospel timing.”

“He had multiple paths from croon to rasp, and he could sound simultaneously forceful and desperate,” The Times wrote of Williamson’s performance.
