I recorded Alabama Song as a solo about three years before the Doors version came out - in its highly truncated, politically emasculated form. They dropped the most important last verse (money) and made the whole thing about SEX. The best performance of Alabama was Lotte Lenya's = she released an excellent double album on Columbia Records around 1957 - right after I had seen her perform the Three Penny Opera in NYC.
The chording of the Trio's version was meticulously done by Paul Prestopino and David Ander, our two great accompanists. How they ever distilled it (from the operatic score) into three parts so well was a wonder to me. I recently asked Paul to repeat that feat and arrange "The Soldiers' Song" from Threepenny for the Trio. He's going to be working on it.
