Question: What is strange about the numbering system used for the 33 rpm catalog?
Answer: There is a chronological incongruence in the numbering of the 33 rpm catalog: after Fabrizio De André's Vol. 1° (BBLP 39) the numbering starts back from BBLP 30 which is the number for I Barritas' La messa dei giovani.
