The group around Paul Thek was working and living in the exhibition spaces. There were also music cassettes playing during the day and Edwin Klein and Michèle Collison used to play the piano. There are still piano notes of that period in the collection of the Museum of Art Lucerne which were bought by Jean-Christophe Ammann (notes of Franz Liszt's "Liebestraum" and Ludwig van Beethoven's "Sonate pathétique" and the sonata for piano Opus 27 no. 2). Previous to the exhibition Thek wrote in a letter to Ammann: "We will need a piano (preferably grand) in one of the rooms... any piano will do (...) it must be permanently there and not be ithe property of another group which continually takes it back (...)" (January 20, 1973). The group brought several books to Lucerne that could be used in the same room, as Jonathan Livingston's "Seagull - a story" or "Love and Protest - Chinese Poems from the Sixth Century B.C. to the Seventennth Century A.D." edited by John Scott. In the letter to Ammann dated Januar 20, 1973, Thek asked also for permission "to work in the museum when we choose, at night for example, with a clear explanation of this fact given to the guard staff (in Sweden we are almost arrested by the museum guard)."
