well, I thought it might be this... but, then I thought, "that's too predictable." john phillips made some remark about cass elliot's weight that caused her to run off from her conversation with mick jagger.
also, john phillips and mick jagger seem to have worked together a bunch. they also didn't release a bunch of this, so there you go.
anyway, I am done with the mick jagger angle. which I didn't really mean to get into, but he just kept coming up... but, I guess if you work with someone that'll happen.
