UK band Dave Dee, Dozy, Beaky, Mick and Tich have had to replace three of their number over the years, but always used the same Stage Name for each musician, even if, in Mick's case, the replacement isn't named Michael in real life. Rhythm guitarist John "Beaky" Dymond was replaced by Paul "Beaky" Bennett, and he was later replaced by Anthony Stephen "Beaky" Carpenter. Similarly, drummer Michael "Mick" Wilson was replaced by John "Mick" Hatchman.
The members of the Village People changed several times, although the personas (Cowboy, Cop, Indian, Biker, Soldier, Construction Worker) remained the same.
In the Eurobeat genre, several different singers may use a certain artist name over time.
KISS provides an odd example: though they still are referred to by their proper names, Tommy Thayer and Eric Singer have taken the makeup designs of their predecessors Ace Frehley and Peter Criss. This wouldn't be an issue, but for the fact that in the past, Eric Carr and Vinnie Vincent received their own unique makeup designs.
The Beatles' version of "Love Me Do" that is heard on the Past Masters CD has Ringo Starr as its drummer. The version that got released as a single outside of the UK and Canada, and on the Please Please Me album in 1963, has Andy White in the beat seat (this version is identifiable by a tambourine played by Ringo), and the Anthology version features original drummer Pete Best.
"Love Is Where You Are" is performed by Diana Krall in the movie At First Sight. While she does appear on the soundtrack album, she performs "Easy Come Easy Go" - "Love Is Where You Are" is sung by Gigi Worth to the same musical backing used by Krall.
Herb of R&B duo Peaches & Herb has always been Herb Fame. But several women have performed in the duo as Peaches, including Linda Greene, who sang the female vocals in their biggest hits "Shake Your Groove Thing" and "Reunited".
Similarly, Country Music group Dave & Sugar always consisted of male vocalist Dave Rowland and a constantly-changing rota of two female backing vocalists as the "Sugar".
At least three musicians have performed with Cradle of Filth as Jared Demeter, including Bryan Hipp, Paul McGlone, and the fittingly named (for this trope) Darren Donnarumma.
The character of Captain Jack was originally performed by a guy who apparently went by the stage name Sharky. He decided to retire after their first hit, and was replaced by the iconic Franky Gee, who stayed until his death ten years later. The group eventually decided to continue with another frontman, Bruce Lacy who plays the character to this day. (They also have a female singer who changed much more often but doesn't portray a specific character.)
