Trying to ID this peice of classical


I'm trying to identify the start of this track by Italian Prog band Quella Vecchia Locanda. I know it and it sounds like Schubert to me but I just cannot remember what the original piece is. Can anyone ID it for me - thanks

Jamscience - That'd be the last place I'd go - and Vivaldi! Good grief - that just highlights what prats that place attracts! Anyway, it's classical experts I need not prog ones (if the latter exists as a concept - and it doesn't believe me!) :)

I'm pretty sure it is Schubert but I am not so confident it's played as in the QVL piece i.e. if it really is a chamber piece. If not, it could solo piano, although it does sound "right" in that track.
This is not Vivaldi. My first thought was Schubert, maybe LvB. Very, very, very familiar.
I have a feeling that the peice is used in the wonderful French film "Péril en la demeure" (aka Death in a French Garden). I have the DVD but it doesn't list the music used in the credits, so I'll have to skim through it to see if it's there. Doesn't exactly help me to ID it but I know that they used Schubert, Brahms and Granados, so one of those is the best bet. I recognise the two German composers styles but am very unfamiliar with the Spaniard.
What do I win? Its Brahms! Piano trio in B major Opus 8. 2nd movement Scherzo!
Brownsfan gets the prize!! Sure sounded like Schubert, though.
