Glenn Miller meets Roy Rogers

Roy Rogers arrives at the pearly gates to be greeted by Glenn Miller. "Hello Roy. We heard you were killed by a mountain lion. Is that right?"
"Yes, unfortunately" says Roy.
"We also heard that you managed to kill the lion before you died. Is that true?"
"Guess so" says Roy.
"OK then" says Glenn "Well a lion has just arrived over there. Go and have a look to see if it is the same one and to welcome you in we'll play your favourite tune as you come through the gates".
"What's that then?" asks Roy.
"Pardon me Roy. Is that the cat you knew who chewed you?"
