Is there a more quintessentially 70's song than...

[Okla-homey]

Dream Weaver?

Man, it makes me wish I still had my '63 Chevy Bel Aire parked at some quiet spot at Lake Murray exploring the nether regions of some unnamed female person.

[crawfish]

It's a close race between that and "Afternoon Delight".

[yermom]

depends on what 70's you are talking about

i'm more of a guitar rock kinda guy myself
