Mellotronists

So perhaps a mind immeasurably superior to mine can answer this:  
Supposedly the first song that Pinder used the 'tron was "Love and 
Beauty" however, I have yet to identify the instrument that was the 
lead in the short solo section of "Boulevard de La Madeleine".  All 
the pre-Hayward/Lodge Moodies stuff featured the piano but this
sounds more like an organ and a very distorted one at that but even 
so, it doesn't sound quite like an organ....any thoughts?
