In 1994 Danish bassist Jesper Lundgaard formed a quartet named The Repertory Quartet in order to make a CD in homage to Thad Jones. The other members were guitarist Jacob Fischer, drummer Alex Riel and tenor saxophonist Bob Rockwell. The CD, titled "This Bass Was Made For Walking", was a great success and the quartet became one of the more permanent groups in Danish jazz - and still is. In 1995 and 1996 the group recorded three more CDs with music by Thad Jones. On the CDs which followed, the group has featured music by Louis Armstrong, Bill Evans, Fats Waller and Charles Mingus. Later on Keith Copeland replaced drummer Alex Riel and in 1997 the group recorded another CD, now featuring music by Duke Ellington and Billy Strayhorn as the theme. In 1999 pianist Ole Kock Hansen replaced guitarist Jacob Fischer.
