Then we are on different planes, sir. Side B of III is probably my favorite side of any record, ever.  "Tangerine" and "That's The Way" are two of my favorite Zep songs, and "Bron-Y-Aur Stomp" is unbelievably fun.  I could take or leave the closer, which I guess devalues my argument a bit, but to steal a phrase from a fellow poster: C'mon man. 
 
  
For anyone who doubts zep III... Bron-Y-Aur-Stomp  with 20 drunks in the room is so amazing and fun.... It's just love man.
