After various personnel changes marked their early formative years, the group solidified their lineup in 1976 with original members Marc Phillips on lead vocals/piano and Tommy Calton on guitar/vocals.
Rounding out the most-popular formation of this group were Lee Bargeron on keyboards/acoustic guitar/vocals, Mike Reid on guitar/vocals, George Creasman on bass/vocals, and Michael Cadenhead on drums/vocals, which is the lineup that recorded their 2 MCA studio albums.
54, becoming the band's highest charting single, and "Hold On To The Night", which reached #80 on the Hot 100, penned by Phillips and prolific 1960s songwriter Barry Mann (co-writer of "On Broadway", "You've Lost That Lovin' Feelin'" and many more).
Founding members Marc Phillips and Tommy Calton promptly created the "Calton-Phillips Group", later changing the name to "Split the Dark".
Notably, one of the final members of Split the Dark was guitarist/vocalist Damon Johnson, who later formed the rock group Brother Cane, which had some national success in the 1990s with three albums, including their biggest hit "I Lie in the Bed I Make".
