whoops, I couldn't tell by your subject line that this was already announced. I had posted it too. I will delete mine.
I particularly never cared for Johnny Cash, especially recently with his version of Nine Inch Nails "Hurt", but it is tragic when someone dies.
Now John Ritter on the other hand, growing up watching his crazy antics on Three's Company and a few B rated movies. I also really enjoyed his current show "8 Simple Rules For Dating My Daughter". It was such a comeback for him because the show was great.
