There may be more than one, but I watched a recent video by a certain C piper who played the hornpipe I’m thinking of on youtube… That video has since been deleted! The name escapes me anyway. ThanX,
Queen of the Fairies is the one you want. O’Flynn plays it on his album The Art of Uilleann Piping.
Not to be confused with The Faery Queen, which O’Flynn plays on his album simply titled Liam O’Flynn.

O’FLynn also plays it on the recently launched NPU DVD: The Piper’s Choice.
The other one that hits top D is The Bee’s Wing. It is on The Drones & The Chanters Vol II, I think.
