im probs gonna get flamed for this but i was just wondering who wrote the song pressure drop? Because i have a version by the clash and a version by toots and the maytals but i have no dates to match the tracks.

it's originally by the maytals, who i never heard of til i looked up this question
"I see my light come shining from the west down to the east
Any day now, any day now I shall be released"

Know any good teachers in NY, especially skilled in teaching ear training? Tell me
