That was shot at the end of October and has been on YouTube for some reason, glad to see it's on regular TV now. I advised him to get paid up front, and not in Radio Shack stock! (which has now dropped to 50¢)

Speaking of parodies. What exactly constitutes a parody? Can it be simply changing the lyrics to reflect even a political or personal opinion of something. Say like the song "All that Bass" rewritten to show corporate, political or even union management greed?
Al/the band could parody the commercial when Radio Shack finally closes its doors.
Would uploading a video on youtube(or other website) be considered as selling the work-even if no money is made on said video or song?
Hard to say, it's likely that YouTube/Google is deriving revenue, however small the amount.
Essentially, the parody itself may be regarded as fair use, but the instant you try to sell the new work, the writer(s) of the original song have to be compensated. The permission process helps establish the percentage that each party is entitled to, and it's smart to sort that out up front.

As was remarked on earlier in the thread, Radio Shack has indeed gone bankrupt. Local RS stores are fire-selling everything. If you need some cheap headphone cables, now's the time.
