What is the biggest rock band with no living, original members?

Reading his Wikipedia page, he was married to actress Mamie Van Doren, who is also still alive, at 95.

Married for six years, divorced for 65.

104 years old? Sounds like a sure thing for my 2027 Death Pool!

Ny concern is “Bands that tour without any original members”.

I go to festivals that include a lot of '60s and '70s bands, but I always google the current lineup (told my kids "I’m going to see One Dog Night!"). And I’m often disappointed by how little the band is like the one I loved back in the day.

A fun surprise was the “Cornerstones of Rock” tour: a great lineup that I made a special trip to see.

With The Ides of March (no, “Vehicle” wasn’t BS&T) as the “house band”, their frontman Jim Peterik acted as emcee. He introduced bands like The Buckinghams, The Cryan Shames, The New Colony Six , and The American Breed.

It was so weird watching grandpas rocking. But those bands sounded just as strong as they ever did…
…although the surviving member of Aliota Haynes Jerimiah belted out “Lake Shore Drive” while hanging onto the mike stand to stay upright.

Some bands only had one guy living, but Standells and McCoys founder (Rick Derringer!) was great, as was Jimmy Sohns (The Shadows of Knight).

.

But there are some bands I’d never go to see now:
The Beach Boys had three different bands touring, each with one or two past mambers. And I’ve heard The Little River Band is a legal mess. Somebody sued to use the name and tour the U.S. while original band members are playing (under a different name?) in Australia.

Any band calling themselves the Beach Boys always includes Mike Love. However, “The Brian Wilson Band” for several years had more original Beach Boys than Mike Love’s group. There was also “Original Beach Boy David Marks” and “Al Jardine & The Pet Sounds Band”. Granted, they all play(ed) Beach Boys songs, but if anybody tries to bill themselves as “The Beach Boys”, Mike Love will have their legs broke.

Renaissance toured for decades without any original members (No, Annie Haslam was not on their first album). They still do occasional gigs.

I’ll throw Gong into the mix. I haven’t until now because they’re not anywhere near “big” as far as the general public is concerned. But they’re pretty big in the context that if someone decides to start getting into progressive rock more deeply than the occasional top 40 hit that comes from a prog band, Gong will likely be among the first groups they encounter.

Considering the folks on the first album, Magick Brother (1970), as the original lineup, we have one still-living participant, Didier Malherbe, a.k.a. Bloomdido Bad De Grasse. But he hasn’t been a full-fledged band member in years.

Gong has a rather tangled and possibly even confusing history. Suffice to say that just before the founder and central figure, Daevid Allen, died in 2015, he encouraged the guys in the band at the time to continue. They did, and they’re still going, giving us Gong’s longest-running stable lineup–with the longest-standing member having joined in 2007.
