I don't know about the orchestra accompaniment BUT
there is a good band arrangement of Capuzzi's "Concerto for Violone" that was done by Luc Vertommen out of Band Press VOF, Watertorenlaan 13, B-1930 Zaventem, Belgium

the elephant wrote:She needs an accompaniment either by Catelinet or one that was specifically done for this version, again, as I wrote. I need to know whether there is such an accompaniment available for hire or purchase, for that specific piece only. Thanks!

I have an idea if you can't find the PC accompaniment.
Simply play the piano part for the Hindemith along with -any- tuba solo and try to pass it off as some whacked out mid 20'th century composition that was only performed once for a doctoral recital at a Unitarian church and premiered during a 3 foot snowstorm on a BBb/F double tuba with a Dr. Young mouthpiece. You know, the kind of stuff Bloke loves to listen to

I'm sorry to see this thread hasn't turned up what you're looking for. I would think a band or orchestral accompaniment to that arrangement could get some good use. (But, I still like the first movement of the Cappuzi, not included in the arrangement, the best - a great movement on CC tuba!)
