Thanks for the link.
From wiki:
The ad hoc group, called The Primitives, included John Cale, who had recently come to the city to study music and was playing with the composer La Monte Young. Cale was surprised to find that for the novelty song, Reed tuned each string of his guitar to the same note. This technique created a drone effect similar to that which Cale's avant garde ensemble had been experimenting with.
Is that true or is it just bullshit?
