"Pushin Too Hard" by The Seeds has been one of my favorite songs since the moment I first heard it sometime in the late 70's. I first thought they were a new punk band at the time and only learned later, they came a decade or so earlier. The song just grabbed me with it's propulsive rhythm and some of the best bratty vocal stylings ever. The nasal annoyance teams with the vocals to give it the perfect "get-off-my-back" attitude.
I've never seen them perform, but the bad lip-synch is worth the price of admission.
