There is apparently a complete recording of this performance, from which the above bits are excerpted. Thanks to Jan Lohmann for providing me with these excerpts.

The Quintet played several venues in Europe in late October-early November 1967 as part of the "Newport Jazz Festival in Europe" produced by George Wein. According to Billboard magazine, groups from the tour were booked in the following cities, although each booking involved a subset of the groups involved: Baden (West Germany), Barcelona (Spain), Belfast (Ireland), Berlin (West Germany), Copenhagen (Denmark), Dublin (Ireland), Epernay (France), Helsinki (Finland), Karlsruhe (West Germany), Lecco (Italy), London (England), Lugano (Switzerland), Lyons (France), Mainz (West Germany), Paris (France), Rotterdam (Holland), Stockholm (Sweden). The Quintet, usually paired with the Archie Shepp Quintet, was booked in ten cities:

October 28: Koningin Elisabethzaal, Antwerp, Belgium
October 29: Hammersmith Odeon, London, Great Britain
October 30: De Doelen, Rotterdam, Holland
October 31: Konserthuset, Stockholm, Sweden
November 1: Kulttuuritalolla, Helsinki, Finland
November 2: Tivoli Konsertsal, Copenhagen, Denmark
November 4: Philharmonie, Berlin, West German
November 5: Teatro Europa, Lecco, Italy
November 6: Salle Pleyel, Paris, France
November 7: Stadthalle, Karlsruhe, West Germany
November 12: unknown venue, Barcelona, Spain

Also on the tour were the Thelonious Monk Octet, the Gary Burton Quartet with Larry Coryell, Sarah Vaughan and the Bob James Trio, and many others. Davis apparently left the tour early (ca. November 10) after a dispute with producer George Wein. The rest of the Quintet performed the final concert or two of the tour as "The Wayne Shorter Quartet."
