I'm a bit late to this thread - and usually lurk here -- but I can't resist a comment because Alden's arrangement of Bubbles got me into playing chord melody with a pick. I don't think it is played with down strokes on the record, nor does it have much string dampening which I also associate with gypsy picking. In the film it is played by Sean Penn on a Selmer D-hole, but the recording doesn't sound like a Selmer. Alden says he wrote it in the style of Eddie Lang and gave it a rubato feel because Penn is just playing it lazily in bed for his girlfriend. He also says it lends itself well to fingerstyle, which is true, but I find it is best played with a plectrum. I was really struck by the different tones and dynamics I could achieve with a plectrum, especially on an arch-top played acoustically. Although not as versatile for chord melody as fingerstyle, using a pick has given me a way of defining my own style. With some exceptions, most fingerstyle arrangements can be easily adapted for plectrum playing by using string skips (or plucking a string with one of your spare fingers) when nothing else will do. These days I usually use real books and play chords and melody with a few arpeggio runs and swinging bass notes to fill it out. I don't see why this can't be done with Gypsy picking - in fact, I have a CD somewhere of Django playing solo. I'm sure everyone knows Django's Tea for Two but this youtube clip has the tab as well:
