I will add more pictures to this one.
On the back cover of my release is stated 6. 56, and that will be the date for the release.
On the first added one here, is stated 10. 58 (56), and will be the date of this release.
I've talked to some German collectors, and they say, that the date that is printed close to "Printed in Germany", with nearly 100% is the date of the release.
Comments to this is welcome.
More yodelling than you could throw a stick at, if you were that way inclined. I'm not sure which group sings what: the two tracks on the 'B' side sound like they're by the same group, the two on the 'A' by different groups... Anyone who's interested can look at the labels and make their own minds up.
