Stockhausen described as "crucial" an orchestral performance in London of "Set sail for the Sun" on 14 January 1970, in which the BBC Symphony Orchestra, rehearsed by the composer, was distributed around the audience in four groups, each with a "core player" from the Stockhausen Group. Other notable performances include the 1969 Darmstädter Ferienkurse, when the groups that had just finished the recordings for DG performed eleven of the texts in four public seminars, on 1–4 September in the Städtische Sporthalle am Böllenfalltor, many of the texts in multiple daily performances from 14 March to 14 September 1970 in the spherical auditorium of the German pavilion at Expo '70 in Osaka, and at the 1972 Shiraz Arts Festival, where a day of "Music in the City" on 7 September featured several component pieces of "Aus den sieben Tagen" performed at various places in the inner city from dawn to dusk.
