What is the epic song of a group?

Obviously Bohemian Rhapsody by Queen possibly the best known Epic group song of all.

A Day in the Life works fine for me for The Beatles as well. I’d also take Twist and Shout.

Echoes by Pink Floyd.

Graceland by Paul Simon

Suspicious Minds by Elvis

What’s Up? 4 Non Blondes

Dream On Aerosmithh

Back to Black - Amy Winehouse

Ramblin Man Allman Brothers

Just Between You and Me - April Wine

Cake  "Short Skirt, Long Jacket"
Aldo Nova  "Subject's Theme"
Night Ranger  "Sister Christian"
Black Sabbath  "Iron Man"
Van Halen  "Jamie's Crying"
Roy Orbison  "Cry'n"
Ringo Starr  "Photograph"
George Harrison  "While my Guitar Gently Weeps"

For me the most epic Deep Purple song would be "Child in Time"

Starman - Bowie
Time of the Season - The Zombies

You Really Got Me - The Kinks

I need to stop these songs are popping in me head in no particular order.
