You know your band is going to be significant when people travel across time to ensure you make your music. Bill and Ted may have had more skill with air guitars than actual guitars, but their journey through time taught them how to rock—and pass their history test to keep the band together. Excellent!
Dr. Teeth and the Electric Mayhem
From: The Muppet Show

Sporting what is, inarguably, the best band name in history (real or fictional) and the most on-brand musicians ever, the house band for the Muppet Show was explosive (sometimes literally) in popularity, relevance, range, and musical virtuosity.
I hope this is the hardest decision I have to make today. But the Muppets are always on top.
This feels like a "choose your favorite child"-level decision.
And hopefully they will be "Most triumphant"
