4. I Hear Mellotron & Moog

Those strings sure sound like a Mellotron.
Because of the way they worked, languid pads were what was played 99% of the time.
Boy, those things were touchy! Having the moving head rack across the tape strips were easy to throw out of alignment. Never had one, but I played a couple. Knew a guy (banker's kid) that one as far back as this song.
And that flute like figure is a Moog or an ARP, but I'm going with the former. ARPs got a little mushy when playing a subdued, clamped-down tone.
