From the Midwest Regional, at Big Pink in Saugerties, NY:

#16 Venus in Furs, The Velvet Underground
vs.
#17 I'm A Believer, The Monkees
Two songs with, shall we say, differing perspectives on matters romantic face off here.

#9 Misirlou, Dick Dale & the Del-Tones (Pulp Fic soundtrack version, sorry)
vs.
#24 Debora, Tyranosaurus Rex
An instrumental faces off against a song that seems mainly to be the titular lass's name repeated with different grunt patterns.

#21 I Can See For Miles, The Who
vs.
#12 1969, The Stooges
A fine object lesson on how hard rock changed a little bit during the decade.

#13 See Emily Play, Pink Floyd
vs.
#20 Fist City, Loretta Lynn
Emily just better not mess with Loretta Lynn's man, or Lynn will POUND her.

#14 One, Harry Nilsson
vs.
#19 Tighten Up, Archie Bell & the Drells
I like the Harry Nilsson original so much more than the U2 version... err, I mean, "bugger off, Three Dog Night, and let Harry sing about the loneliest number."

#11 Hold On, I'm Comin', Sam & Dave
vs.
#22 Kick Out The Jams, MC5
I didn't think I knew #11, but I assure you, I know the opening brass riff. You know it. The whole of America has this embedded in its mind within five months of being born or moving here. It faces off against a song known for having a real dirty word right up at the front of it.

#10 Doctor Who (Original Theme), BBC Radiophonic Workshop
vs.
#23 Laisse Tomber les Filles, France Gall
I'm not quite sure if this is the original original Dr. Who soundtrack; if you notice it's not, HA HA, YOUR A BIG NERD. It faces off against a swingin' Serge Gainsbourg-penned track. Even if you don't speak French, you know she's young and the song's probably a little dirty.

#15 Stand By Me, Ben E. King
vs.
#18 Season of the Witch, Donovan
One of these was played at most of my high school dances; the other's title accurately portrays what those dances were like.
