Singer John Denver's tour of ESTEC included an impromptu lunchtime concert in the top-floor restaurant on 22 November 1982. The well-known folk singer visited the establishment as part of a European concert tour, and visited the Exosat flight model in the ESTEC Test Centre. At the time Denver, an experienced pilot, was in talks with NASA about becoming a non-technical passenger on Space Shuttle mission STS-8 the following year.
