How much more entertaining would a broadcaster be in a blissful dream state than in the normal state of a 52 year old with all the associated aches and pains. I hope and pray he makes it, but the creative manic state may be hard to achieve naturally.
If anyone can do it Rush can, though it is not the end of the world if he does not return to daily broadcasting. He already has made quite an impact and in the unfortunate chance that he retires, others will come.
I haven't watched Andy in double digit years. To me he always sounds like he's whining. I wouldn't miss this one though.
