Jerry. Nice, thanks for those impressive demo vids. Interesting that both your links and the ones earlier in this thread demonstrate RH melody utilizing 'button style' keys vs 'piano style' keys. Other than the familiarity for people who come from a trad keyboard playing background, what (if any) are advantages of RH: 'buttons' vs 'piano keys'?

In the meantime, I found this YouTube instructional " How To Play Accordion " Clip Series. Synthzone Accordion experts (Fran, DNJ, Musicman22, JC,miden, etc) : do you guys recommend this (or other) instructional video for an accordion wannabe beginner like myself?
