If you’re out on a long somewhat creepy stretch of road late at night
Stairway to Heaven
Hotel California
The Doors’ The End
Nick Cave’s Where the Wild Roses Grow
Sweet Caroline … Bah Bah Bah … good times never seemed so good.
On a similar bus trip when I was a teenager, someone had a cassette of the Grease 2 soundtrack. Everyone knows the Grease songs, but a busload of horny teenagers singing along to “Reproduction” is hilarious. We wore the tape out halfway thru the trip! 
And I’ll second They Might Be Giant’s, the Flood album is great.
Ever since my brother and I were tiny, the primo car singalong album has been Paul Simon’s Graceland.
The ultimate sing a long song for a road trip is Good Morning Starshine.
Other fine song include
Another Saturday Night
We will Rock You/We are the Champions
What a Wonderful World (Sam Cooke Don’t know much about History)
Here Come the Sun
Octopus’ Garden
Yellow Submarine
All Together Now
Hello Goodbye
Sympathy for the Devil
Peace Love and Understanding
Come on feel the noise (sp?)
Elephant Love Song Medly from Moulin Rouge
Friday, I’m in Love
Centerfold
Love Stinks
Devil went Down to Georgia
OK, some of these may not be appropriate, I’ll let you decide.
Truckin’ - Grateful Dead
You all are doing a great job. Keep 'em coming!
My son has added Kiss’ I Wanna Rock and Roll All NIght, and AC/DC’s Highway to Hell to the list of suggestions.
The sponsoring organzation for our mission trip, Reach Workcamps, plays tracks from They Might Be Giants Flood album for the 6 AM wakeup music.
Highway to Hell is kosher on a church outing? I guess I could have stretched my list a bit then
As for Kiss’ I Wanna Rock and Roll All Night, my friend confessed recently that for many years he thought the following line in the chorus was, “…and part of every day” (instead of “and party every day”). Now every time I hear the song, I think of how old the song is (and how old the band members and ourselves are) and think that the song is really more applicable that way now.
Other suggestions:
Beatles - “Hey Jude”
Norman Greenbaum - “Spirit In The Sky”
Rolling Stones - “Shine A Light” (from “Exile on Main St.”)
Don MacLean - “American Pie” (surprised nobody’s mentioned this one yet!)
Eric Burden and the Animals - “House of the Rising Sun”
Aerosmith - “What It Takes” (maybe even, “Dude Looks Like A Lady” 
)
Lots of Dire Straits.
The entire ‘Born in The USA’ album
The Eagles ‘Greatest Hits’ album.
We all got drunk as sailors one night out camping and we couldn’t think of any songs to sing, so we started singing Christmas carols. Mind you, this was in the middle of July, about midnight. Before long, half of the campground had joined us.

Everytime that happens, God Kills a kitten.
