New Game: Twin Songs of Different Mothers

QAS2: The Cars and the Everly Brothers
Bye Bye Love, my favorite Cars song.

QAS3: Van Halen & Cream
Were you going for Cream’s Sitting on Top of the World and Van Halen’s Top of the World? I can’t think of any others.

QJC1 - Sunny Day Real Estate and Led Zeppelin

QJC2 - Rush and Golden Earring

QJC3 - Rush and Voxtrot and Fountains of Wayne

QJC4 - Avril Lavigne and Velvet Revolver

QJC5 - Sebadoh and Tool

QJC6 - Incubus and James Taylor and The Refreshments

Batteries Not Included
QB#6 - Godsmack and the Spice Girls

I don’t think anyone got this one either:

Q#2 Bon Jovi and Pink and Linkin Park
(it would be giving it away to say who had a big hit with this name in 1961 - but I will clue that this song and artist were referenced in other songs by Tom Petty and BareNaked Ladies)

Yup. Still open:

I think Cinderella did a song called Save Me too.

QAS1: Best of My Love

QA7: Gloria (also Enchantment and Laura Brannigan)
QF5: Dwight Twilley and Bruce Springsteen

QF6: Dwight Twilley and the Beastie Boys

That’s the one I was thinking of. But I realized just too late for the edit that there’s another valid answer for Jethro Tull-Sparks:

“Ladies”

I’m On Fire
And no, “Top of the World” was not the link between Van Halen and Cream.

Thought of another one!

QFS4: Frankie Lymon and the Teenagers, Alana D., and the Vibrators

QR6: Eddie Money, Ozzy Osbourne, Aerosmith, Neil Diamond

AR6: Walk on Water

QR8: Eddie Money and Thin Lizzy

Yessir.

QAS9- Kansas, Triumph, and Wilson Phillips

QAS10- Neil Sedaka and Led Zeppelin

QAS11- Ringo Starr & Def Leppard

And Van Morrison
