You name the group/artitst

Bob Marley

Josie

Blondie (appropriate for today )

You and Me Against the World

Chuck Berry?

Fire and Ice

I had to look that one up...

Pat Benatar

All Mixed Up    

(It's my favorite song by this band too, and you get extra prestige if you know the song that leads into it.)

Madonna

Hair of the dog

Well, you got mine wrong.  311 is not in the 50's to 80's time period.  I meant the song by The Cars, and it segues from the "Moving In Stereo" song.

For The Love Of Money is The O'Jays (money, money, money, money...)

Take A Pebble

HnS, well, I'm not sure about the posts overlapping, but when I posted the "correct" answer, there was no mention about The Cars songs in your post.  We must have been posting at roughly the same time.  I thought that would be a fairly easy one because I do hear classic rock radio play those songs once in a while, tho' they don't play them together like they used to back in the day.  I give you full prestige now.  I'm sure you tossed and turned all night just wondering when the prestige would be arriving, right?  Also, pity if your BIL has those ears!  ;-)

My new one is by a 70's progressive power trio. 

The Impressions (as in Curtis Mayfield and the...)

Peace Frog

The Faces (or maybe Rod Stewart on his own?)

Too Busy Thinking About My Baby

(This has 2 correct answers, one group, one solo.  See if you can get both, but one is o.k.)

Seals & Croft

Horse With No Name

(Yes, HnR, the Temps did that one too.)

Freda Payne

Get On The Good Foot

Peter, Paul, & Mary (I learned that song at camp -- loved it!)

Horse With No Name

Lou Reed

Lola

Jefferson Airplane

(I know; I thought it had been trumped by Shannon's.  But now I see she edited her original answer to answer mine . . .)

Cast Your Fate to the Wind

Funkadelic

It's Closing Time
