A couple of Aussie bands with more than one lead singer: The Whitlams and Spiderbait.
Also, Crowded House has a few songs with Tim Finn in the drivers seat, IIRC.
yeah, thumbs up for spiderbait. kram must be one of the best singing drummers ever.
but the whitlams? there are hardly any regular band members other than tim freedman, let alone singers! or did that guy who died (i forget his name) sing.
also, brissie band george make sweet jeff buckley tinged pop, sung at times by katie noonan, and at others, by her brother tyrone.
I already said Queen. 
There’s also the Kinks – Ray Davies was the usual lead singer, but Dave Davies sang lead on a few songs as well.
Guitarist Stone Gossard has sung lead on a couple of songs for Pearl Jam.
Heh. I’ve known Archie since high school (IIRC, Semp, he’s the one that did the male lead vocals for the band). Used to go see Velocity Girl back when Bridget was still singing for them.
Back to the OP, and referencing a recent thread, all four of the Bangles handled lead vocal duties at one time or another. Not a lot of people probably know that since Susanna Hoffs ended up being the lead singer on most of their singles, which is one of the things that ultimately led to the band’s demise.
OASIS!
To my knowledge, the only song Nancy Wilson ever sang was “These Dreams.”
The Whitlam’s cover of Bob Dylan’s ‘Tangled Up In Blue’ has some other bloke singing. Tim Freedman takes a back-seat some of the Whitlam’s older songs too, IIRC.
Tears For Fears
The Sugarcubes
Buffalo Springfield - The songwriters usually sang their own material.
The Byrds.
Guster!
They harmonize on most tracks, but Ryan Miller and Adam Gardner will trade lead vocal pretty often. And don’t ask me which one is which…

Never! We need more metal threads. I was also glad to see Mehpisto mention Lacuna Coil. I’ll add Theatre of Tragedy and Opera IX. Both death metal. Theatre of Tragedy has an excellent clean female vocalist and a male death vocalist. Opera IX has two female leads that both sing deathy parts. KISS has a main singer Paul Stanley but Gene Simmons also sings lots of songs. The Clash had Joe Strummer and Mick Jones. Rancid has Tim Armstrong and Lars Fredrickson. If we are counting The Traveling Wilburys as a band then add The Highwaymen with Willie, Waylon, Kriss, and Johnny. Jefferson Airplane had Grace and Marty. Biohazard has Evan Seinfeld and Billy Graziadei. One could argue The Who had two with Roger and Pete. Would The Beach Boys count with Mike Love and Bryan Wilson? I guess we need to define terms here…
I 'd say the most legitimate ‘band’ with more than one would be the Eagles with with four, Glen Frey, Don Henley, Timothy Schmidt (sp?) and Joe Walsh, followed by Fleetwood Mac with three.
NP: In Flames - Whoracle
How about Dance Hall Crashers? The lead vocals on just about every song of theirs are harmonized.
Goo Goo Dolls, Nine Days.
Also, Toad the Wet Sprocket. Glen Phillips sang lead most of the time, but Todd Nichols sang quite a bit too.
The Bee Gees.
God help me, that’s the only band I could think of that wasn’t a rap group (The Beastie Boys came immediatly to mind)
Don’t forget the Donna and Keith Godcheaux years where Donna often sang lead. Phil also gets the nod on a few songs: Box of Rain, Tom Thumb Blues . . .
Well, I dont think anyone mentioned Frank Zappa yed, did they?
Form 1970-17 there was Flo and Eddie
From 73-75 there was Zappa, George Duke and Napoleon Murphy Brock
From 75-77 it was Zappa, Ray White and Terry Bozzio
From 78-84 it was Zappa, Ray White and Ike Willis
…had three lead singers, Danny Hutton, Chuck Negron, and Cory Wells.
Crosby, Stills, Nash, and Young. With lead vocals by Crosby, Stills, Nash, and Young. (-:
GEEZ, where are the BOOMERS?
We get Norwegian death metal bands and NOBODY has come up with JEFFERSON AIRPLANE ?
That would be Marty Balin AND Grace Slick. Remember how cool it was when he returned for “Miracles?”
Sigh.
Must be gettin old
It’s 80’s flashback time…
The Bangles
The Go-Gos
