The “Spinning Wheel” that is Blood, Sweat & Tears has spun through more than 200 members in its 54 years.

“From the very first album, we’ve changed members,” said Larry Dorr, who’s managed the band for 40 years. “You ask someone their favorite member, and they’ll say (singer) David Clayton Thomas. Well, he’s not an original member. He came on the second album.”

Musicians have gotten their start with the band, played with it for a few months or a few years and pursued other musical interests. In some cases, the band has brought in performers who gained notoriety elsewhere first. The current lead singer for the band, which will perform Friday at the Robins Theatre in Warren, is Keith Paluso, who competed in Season 15 of “The Voice” as a member of Kelly Clarkson’s team. Bo Bice, who was runner-up to Carrie Underwood on season four of “American Idol,” also was a former lead singer with BST.

“It keeps everything fresh,” Dorr said. “Musicians get bored easily. When you’re playing the same music every year, you get bored and you can tell they’re bored. Change is good for the band. It keeps them young, keeps them thinking on their feet.”

That said, it takes a particular set of skills to handle the repertoire of the band, which had pop hits in the late ’60s and early ’70s with songs such as “You’ve Made Me So Very Happy,” “Spinning Wheel,” “And When I Die,” “Hi-De-Ho,” “Lucretia Mac Evil” and “Go Down Gamblin'” but always had a stronger jazz influence than other horn-driven rock bands of that era.

Founding drummer Bobby Colomby no longer tours in the band, but he’s involved with selecting the musicians who do.

“Every rock guy thinks he can play jazz and seldom can they ever,” Dorr said. “Bobby Colomby comes from a jazz background and we kind of really look at jazz players first, see what their jazz chops are first. Every bit of music Blood, Sweat & Tears catalog has jazz roots.”

Those original songs were designed to allow for improvisation, and the band still embraces that approach. But Dorr said the band also knows many in the crowd have memories attached to that music and want to hear the songs performed as they remember them.

“We stay true to that music,” he said. “No one wants to hear a song they got married to, that they listened to when they were in Vietnam, whatever, and not even recognize it anymore.”

The band does continues to add new music to the set. Its arrangement of Duffy’s “Mercy” has become a crowd favorite, Dorr said, and the Allman Brothers Band “Midnight Rider” is another song that’s gotten the BST treatment.

“When we first started doing it seven, eight years ago, I was against it,” he said. “No Blood, Sweat & Tears fan is going to go for this. But they rearranged it, and it’s one of our biggest songs.”

The band’s core fan base are those who are old enough to remember when the band’s self-titled second LP spawned three hit singles and won the Grammy Award for album of the year in 1969. But the band’s music never went away. Marching bands still play “Spinning Wheel.” BST and its songs have been mentioned on “The Simpsons,” “Sex and the City” and “The Sopranos.”

“We’re probably one of the luckiest bands on the planet,” Dorr said. “Everyone has some sort of memory of the band.”
