Though they were technically the third incarnation of the dreaded Fearsome Foursome to dominate the Sunday gridirons, the Los Angeles edition (1963-1967) is probably the most notorious -- and I mean that in a good way, both on and off the field. Don't believe me, well, check out their appearance on Shindig:

It was released in 1965, so Greer was still with the team, but I have no idea if Greer provided the vocals for this, though everyone on the web seems to think so. I've spun it a few times on YouTube and it sounds like him, but that photo's a definite puzzler so I can't say for sure that it definitely is him. If anyone does know, please sound off. Thanks!
