Top 10 Songs Featuring a Mellotron

The best space rock song.

The keyboard intro is all Mellotron; when I heard it, I was immediately transfixed by the tonality and the depth of the sound.

I had completely forgotten about this song. I was thinking about it and realized that it does have a Mellotron on it. Strings, to be more specific.

The choir sounds in the background are from a Mellotron. It also sounds like Jonny Greenwood used it on The Tourist (please don't quote me on that, though).
Edit: Turns out, it was indeed used on The Tourist.

Brian Jones played the rhythmic horn parts on a Mellotron. George Chkiantz, the studio engineer, said that he was impressed by Brian's ability to get a tight performance because of the fact that a Mellotron has a slight delay between pressing the key and hearing the sound.

That cello you hear during the song is actually Bonehead (the rhythm guitarist) playing a Mellotron. Oasis also used one on Don't Look Back in Anger, Cast No Shadow, Falling Down, The Hindu Times, Go Let It Out, and Magic Pie.

From "The Village Green Preservation Society". The flute parts throughout the song come from a Mellotron.
Edit: So does the electric guitar.

Producer Al Kooper added Mellotron strings to the song. He did the same thing for Free Bird, but the strings on Free Bird are out of tune.

Bob Seger's keyboardist played a Mellotron on it, live. Just touring with a Mellotron takes a lot of gumption.

The strings that you hear in the background are played on a Mellotron.
