Bright colored pinwheels go 'round in my head.
Wow, thank you so much for this information! I got my first Alfa and Canyon discs this year, so I am now becoming familiar with these names. It seems to me that the Alfa discs are the earlier pressings (38XB and 32XB), and Canyon/Pony Canyon are later pressings (D32Y..., D50Y..., etc.). My 1985 disc of "Singles" is with Alfa, but my disc from either the next year ('86) or the year following ('87) for "A Song for You" was with Canyon.In 1986, A&M left Alfa Records, and signed a Japanese distribution agreement with Canyon Records (which was renamed "Pony Canyon" in 1987, following a merger with Pony Records). In 1989, Herb and Jerry sold A&M to Polygram. Polygram ended the agreement with Pony Canyon (likely by buying out the contract). Polygram was later sold to UMe.
Neither Alfa Records, nor Pony Canyon, was ever owned by Polygram or UMe. Alfa Records was purchased by Sony in 2000. Pony Canyon was, and continues to be owned by Fuji.
