[78-L] Smith and Dale --- Dr. Kronkheit sketch

[L78rpm at aol.com.invalid]

I am trying to locate a sound recording or film version of them doing this  
skit.  
 
Does it exist in any form?  Does anyone know?
 
There is an LP called Smith and Dale at the Palace.  Does anyone have  it?  
Is the skit included?
 
Long ago, I saw them perform this skit, perhaps on the Ed Sullivan  show.
 
Any help offered will be appreciated.

P.S.  Their fireman skit is up on youtube.  But their famous Dr.  Kronkheit 
skit?  I can't find it online except as partial text  transcription.
