I think in this case. simple and straight forward is best for this minute long piece.. I tire from listening to performers. "stretching out phrases", "lingering over notes', playing with "exaggerated rubato" etc. I think much more is made out of this simple fresh piece of music, than what is was meant to be. I played it much more the way you are describing in my 2010 album, but my interpretation of it has changed, and it is how I like it. I can tell you one thing--if you listen to the piano rolls and early recordings of Grieg playing his music, it is quite simple and direct, and devoid of affectation. When I listen to it, I hear a different "kind" of romance.
