I hope some day the Tübingen concert, from the 1961 European tour, will be cleaned up and released. I believe it's the only recording, of presumably four total, from this tour — the others being Bremen, Stuttgart, and Graz — that has not seen a digital release.
The Jazz Discography Project lists eight titles from this performance, if "western Europe" is indeed the Tübingen set. Unique Jazz released a boot on vinyl. Here it is. The music is great; a fair amount different than the performances from the other cities.
