The 'Scherzo no. 2 per orchestra' (1957) takes 12'02 on the Donemus recording (Brabant SO under Marc Soustrot). It will be performed in Utrecht in a concert in two weeks. I'll register the timings. ;)
Plus: Willem van Otterloo conducting the Residentie Orchestra (The Hague) in the Second Symphony (same recording as on the CV cd). This one is found on cd 9 of the 13cd box by Challenge Classics CC72142 (subtitled: The orginal recordings 1950-1960).
