“The Magic Fountain” from Glamour Suite No. 1 by Harry J. Chalmers. Two pages long, easy to learn, very schmaltzy, but people love it. Also out of print, I’m sure, so you’d have to search for a copy. Listed as “Solo for Harp or Piano”, but I think a pianist would have to substitute arpeggios for the glisses. Lots of easy arpeggios, something like the ones in Sam Pratt’s Fountain piece.
