Thanks for that, 55Bluesman! I saw the "Club-Sonderauflage"(Club Special Issue) on the label but thought Phonogram might've had the issue in its usual(for that time) numbering system but might've had a special "series number prefix" set aside for these releases.(the four digits at the beginning of these numbers are generally, I believe, a 'series' number, the following three numbers are the album's number within that series, method applied also to singles and cassettes).
I find it somewhat odd that this 1972-issued LP would be using an earlier numbering system(5 digits in a two-digit followed by three-digit format) when Phonogram was using, at that time, a 4-digit/3-digit numbering format for both singles, LPs and cassettes. Is this LP a 1972 reissue using its original number from the 1960s?
