It always makes me sad to watch Eric. He was not only an outstanding musician (the recitals together at the IDRS conferences in Redlands and Georgia will remain unforgotten) but also a sincere and honest friend. His completely unexpected death (so soon after his last visit with us and our trip together to the Königsee and Neuschwanstein Castle) has left a wound that will not heal. It makes me proud and happy that I was allowed to be your friend. RIP.
Bassoon's timbre is ideal for this but I cannot deny the E5 at 0:46 is missing sorely. I'm no bassoonist but I think it's possible; difficult and capricious but possible (and like most magic with double reeds: there's probably a reed design facilitating the task).
