Ongaku Senka, 1979 (Japan)

1st edition (pink writing), published in 1979, features a report on Knebworth 1979 with many color photos from the shows. The small column on the lower-left corner of the cover can be read as “Ongaku Senka デラックス（Deluxe）”.

2nd edition (blue banner/edition 1), published in 1981, features a report (and photos) from “Tour Over Europe ’80” in addition to the Knebworth report. A thick blue line runs at the top of the cover and the column can be read as “解散!! “(Kaisan!! = disbanded!!).

3rd edition (blue banner/edition 2) published in 1982, this almost identical to the 2nd edition but the small column can be read as “再編!?” (Saihen!? = reunite!?). Also, the company ad on the backside of the front cover is different than the one on the second edition.

The 2nd and 3rd editions are distinguishable by “!!” for the 2nd edition and “!?” for the 3rd edition.
