Mellotronists

Hi,

I have Court of Crimson King, Wake of Poseidon, Red, and Starless+Bible 
Black.

I'm wonder *how much* Mellotron is on the other early period albums 
Lizard, Larks Tongue, Islands.  From what I gather, no major epics like 
Epitaph, Starless, Wake of Poseidon.  

I like their other material that sounds like actual songs, not too 
crazy about the really experimental stuff like Providence.  Unless 
there's pretty prominent Mellotron, I'm not in any particular hurry to 
buy any of the other albums. 

Can someone clue me in; thanks....
