Anyone knows the name of this instrumental?

[drgnk]

Further to this I can at least find the tracks on his album
Mozart 13 Serenata No. 13 In G Major "Eine Kleine Nachtmusik" KV 525 A1 Allegro 3:40
A2 Andante-Romanza 3:34
A3 Menuetto 2:07
A4 Rondo 2:39
Aria From "The Marriage Of Figaro" A5 Que Es El Amor 3:05
Vocals [Interpreted By] - Maria Lalanne From "The Marriage Of Figaro" K 492 B1 Overture 3:25
Mozart 21 (Concerto No. 21 For Piano And Orchestra In C Major) K 467 B2 2nd Movement "Andante" 5:14
Broma Musical (A Musical Joke) K 522 B3 "Presto" 2:31
From "The Magic Flute"

Although I have not heard it there is one called a musical joke which I believe is a term used with Eine Kleine Nachtmusic hence it could be that !

Thanks gryphon. I will check it out (Waldo De Los Rios - Mozartmania, 1972.). I was suggested on several forums that it could be Rondo Veneziano but they were not so shore either. There is a lot of resemblance regarding the style, though.
