Comment by PhilMH:
Despite the copyright date, this wasn't a 1974 release anywhere in the world; in the US, the sleeves and labels had already gone to the printers when Dylan decided to re-record 5 songs, and those re-recordings weren't completed until 30 December 1974, with original US release of the album being on 20 January 1975. Australian release was probably the same week or the following week, as the album entered the album chart for the week of 10 February 1975.
And PC 33235 in brackets is just a reference to the US catalogue number, it wasn't an Australian catalogue number at all - that's Discogs-think which is spreading a little too much for my liking!
