 Verlon Thompson was the band's original lead singer, but he was replaced by Stewart before the band signed to RCA Records Nashville.
 Stewart departed for a solo career in 1992; during this time, Innis, Gregg, and Dittrich alternated as lead vocalists, until Innis also left.
 The band was on hiatus from 1994 to 1998.
 During this hiatus, Dittrich briefly recorded as one-third of The Buffalo Club, and Jennings joined Vince Gill's road band.
 Stewart, Gregg, Dittrich, and Jennings reunited briefly in 1998 to record new material for a greatest hits album; they, along with Innis, reunited again in 2004, and this lineup has remained ever since.
Rainbow (also known as Ritchie Blackmore's Rainbow or Blackmore's Rainbow) are a British rock band led by guitarist Ritchie Blackmore, active from 1975 to 1984, from 1993 to 1997, and from 2015 to the present.
 They were originally established with Ronnie James Dio's American rock band Elf, but after their first album, Blackmore fired the backing members and continued with Dio until 1979.
 Three British musicians joined in 1979, singer Graham Bonnet, keyboardist Don Airey, former Deep Purple bassist Roger Glover, and this line-up gave the band their commercial breakthrough with the single "Since You Been Gone".
 Over the years Rainbow went through many line-up changes with no two studio albums featuring the same line-up.
 Other lead singers Joe Lynn Turner and Doogie White would follow, and the project consisted of numerous backing musicians.
 A pioneer to power metal, the band's early work primarily featured mystical lyrics with a neoclassical metal style, but went in a more streamlined, commercial direction following Dio's departure from the group.
