Mellotronists

Would the John Peel BBC sessions OMD release "1979-1983" be the only 
Peel Sessions release to contain Mellotron? I see there are two 
versions--one with fourteen tracks, and another with fifteen tracks- 
the bonus being a version of "Electricity". I only found out about 
this OMD release recently on a discusson board asking everyone what 
their fave Peel Sessions disc is. (Mine is the double LP by Soft 
Machine on Strange Fruit). Anyone have this and what did you think 
of it? I see it appears to be long out of print, but still easy to 
obtain at a decent price.
