The most '60s song

I was just on hold waiting for some technical support and I heard Red Rubber Ball by The Cyrkle. It made me wonder what song is most emblematic of the '60s - the song that when you hear it you are instantly transported back to that era, not necessarily the most popular song of that time. And maybe not even a song you like - for example,the awful Convoy might be very representative of the '70s.

My vote would go to Incense and Peppermints by Strawberry Alarm Clock.

At the risk of looking like a blogger just trolling for comments...what do you think?
