Why did I forget the Sparton?

The LP "Swedish Jazz; Gosta Theselius and All Stars" was published 1956 in the USA by Bally and in Canada (also the UK?) by Sparton – the same record with number 12002. The Canadian Cover has the Sparton name printed along the upper edge on the Bally cover. Sparton printed their own red labels – Bally's were blue.
This session was brought to my attention by Bengt-Arne Wallin, who recalled a session organized by a Belgian producer (Jacques Kluger).
A Swedish issue appeared some twenty years later on Gazell. Lars solos on Cool and Cozy, The Swingin' Thirds and his own Bugs. The second baritone solo on Cool is played by Lennart Jansson.
