Ozzie Osbourne–“You Can’t Kill Rock and Roll”…his best ballad in my opinion.
Great suggestions folks!
Adding to my own list:
The Who - Long Live Rock (rock is dead)
Loggins & Messina (also others I think?) - Your Mama Don’t Dance (& your Daddy don’t rock 'n roll)
Seems like there has to be some appropriate John Lennon but I haven’t come up with it.
Need some more female voices.
I just did a search and found http://rcs.law.emory.edu/rcs/
The one I like is “Rocanroleando” by Freddie Fender.
Blasphemy, no one has mentioned Kiss yet.
I wanna rock and roll all night, and party every day!!!
How 'bout “Rock and Roll” from the Coup D’Etat album by the Plasmatics, voiced by the lovely and talented (and dead) Wendy O. Williams?
Jon
Kinks:
Rock and Roll Cities
Rock and Roll Fantasy
“…it’s only knock and knowall, but I like it.”
—Genesis, “it” (from The Lamb Lies Down on Broadway)
The list is starting to shape up like this:

Billy Squier - Rock me Tonight
Bloodrock - You Gotta Roll
Bob Seger - Old Time Rock 'n Roll
Boston - Rock & Roll Band
Byrds - So You Wanna Be a Rock 'n Roll Star
Chuck Berry - Sweet Little Rock’n Roller

Dobie Gray - Drift Away (Give me the beat, boys…)
Elton John - Crocodile Rock
Four Counts - Rock ‘n Roll is Good for the Soul
Heart - Rockin’ Heaven

Huey Lewis - Heart of Rock 'n Roll
Jethro Tull - Too Old To Rock 'n Roll (Too Young to Die)

Ozzy Osbourne - Can’t Kill Rock and Roll
Queen - We Will Rock You
Rick Derringer - Rock 'n Roll Hoochie Koo
Steve Miller - (Keep on) Rock’n Me (Baby)

Those I have and like for the list. I decided against Cover of the Rolling Stone (Dr Hook) and I Dig Rock and Roll Music (Peter Paul & Mary) which I also have. My copy of Beatles’ “Rock and Roll Music” is damaged so I’ll need to get a better copy. And I’ll need to buy or borrow these:
Twisted Sister - I Wanna Rock
John Cougar Mellencamp R.O.C.K. in the USA
Rolling Stones - It’s Only Rock and Roll (but I like it)
AC/DC - For Those About to Rock (we salute you)
The Who - Long Live Rock (rock is dead)
Bad Company? or Kinks? - Rock and Roll Fantasy <-- not sure which version I’ve heard
dont’ know these two but I’m curious:
Danny & the Juniors - Rock and Roll is Here to Stay
Plasmatics (Wendy O) - Rock and Roll
Blue Oyster Cult - Blue Oyster Cult - Cities On Flame :
http://www.lyred.com/lyrics/Blue+Oyster+Cult/Blue+Oyster+Cult/Cities+On+Flame/
Blue Oyster Cult - Spectres - R. U. Ready 2 Rock

Well, to be honest, and speaking as a Plasmatics fan, “Rock and Roll” isn’t one of the Plasmatics better songs. You really do have to check out the Supersuckers and Electric Frankenstein songs though.

Another KISS great one: “Let Me Go, Rock and Roll”
The Ramones -Rock and Roll High School
David Bowie- Rock and Roll Suicide
BB King- Rock me Baby
BB King- Hail Hail Rock and Roll
Rose Tatoo-Rock and Roll Outlaw
Brian Adams(I think) Everywhere we go the kids want to rock(?)
nitroglycerine:
OK, I’ll add them to my “curious & must check out” list 
I’m surprised Bob Seger’s “Turn the Page” hasn’t been mentioned yet. It’s not really about rock music, per se, but about the difficult life of a rock band being on the road and touring.
Another AC/DC tune that fits the bill:
“Rock n Roll Ain’t Noise Pollution”
As Mr. Johnson so aptly states in said tune, “Rock n Roll ain’t no riddle, man. To me it makes good, good sense!”
I love that song. 
Jammer
Paul McCartney - “Venus and Mars/Rock Show”
Davie Bowie - Ziggy Stardust - pretty much the whole album.
Moody Blues - I’m Just A Singer In A Rock And Roll Band (though I hardly consider that song rock n’ roll)
Black Rebel Motorcycle Club - Watever Happened To My Rock And Roll
The Mekons - Memphis Egypt (not titular, but referenced many times within the song, and off the album entitled Rock ‘N’ Roll. Many of the other songs on the record relate to aspects of Rock And Roll history, such as Eric Burdon and The Animals touring the south US in the 60’s just as the civil rights movement was at it’s highest and most violent point.)
Another couple are -
Elton John - Crocodile Rock
Billy Joel - Still Rock And Roll To Me
I have to say that I would consider those more to be novelty pop though, and pretty antithetical to true rock.
In rereading the OP it sounds as if we’re looking for songs that are about rock 'n roll, not just those with the words in the title. If so then most bands have a song either about life on the road (genarlly seen as a drag, excepf for all those lovely dollars) and/or about the hucksterism and corporate BS that goes with the territory.
Examples of the former
Little Queenie by Lynyrd Skynyrd about an evening with a groupie
**Wanted: Dead or Alive ** by Bon Jovi
Homeward Bound by Simon & Garfunkel, though more folk-pop than
rock 'n roll, is plenty evocative with it's "every day's an endless stream of
cigarettes and magazines"
And, of course, dwc1970 pointed out one of the absolute classics, the
mesmerizing **Turn the Page ** by Bob Seger, with the incredible sax work
Examples of the latter
Workin’ for MCA Lynyrd Skynyrd
The Powerman by The Kinks, from “Lola vs. the Powerman & the
Money-Go-Round, Pt. 1” In fact, other songs on the album lash out at
different aspects of the business
