I posted last Thursday about channel 9 news and their apparent use of the F bomb. It was brought to my attention by Daniel that Tesla did have a radio version of "Signs" that replaced the F bomb with "blockin". I have to believe if given the chance, they opted for the radio version. We'll give them the benefit of the doubt.
And yes, Steve, I did have the Tesla album. I couldn't help but be mesmerized by the five man acoustical jam!
