One song in general...
Little Willy & The Adolescents-Get Out of My Life
Also keep in mind (because I had once thought the same thing,) many of the great organ work you hear in 60's Punk or Revival stuff isn't always the sound of a Farfisa, but the sound of a Vox Continental. I'm not trying to be a snob or anything, just offering some knowledge. The sound of the Continental is amazing. Nothing pleases my ears more in the Organ vein.
You also can't go wrong with ? & The Mysterians...because just about every song has some catchy Organ in it.
A new group that used a Farfisa organ that I can think of is Thee Allmighty Handclaps. I wonder what happened to them.
