"Disappearing" lyrics

All the people you knew were all mad at you
All the people you knew crowded the avenue
If you're not appearing then you're disappearing
If you're not appearing then you'll disappear

You're looking pale, here, take a vitamin
Open the door, please, let some sunshine in
If you're not appearing then you're disap-
If you're not appearing then you'll disap-

If you go down to Memphis
Please don't go swimming in the Mississippi River
If you must, if you do
Take off your jacket and take off your boots
Just don't wash up on Beale
