Everyone knows at least one song Udo Jürgens, even if he is not aware of any. This already shows that this is certainly is not a 08/15 artist or even a flash in the pan.
Of course, just for the younger generation all but rather frumpy, but when the album like this one as a gift to a Udo Jürgens fan to his 66ten birthday is well received and has no objections, these may best of probably not be bad!
