The Accordion Café (free)

Hey Guys,

I have a small accordion with only five rows on my left hand, without the diminished chord button row. For "Irisha" (that I find really really cool) I have been helping myself playing the C° and C#° Chords with 3 Base and Counterbase single tone buttons and with the "Frank Marocco Left Hand Accompaniment", it seems to kinda work. I wanted to ask, whether any of you guys also uses chords composed only of base tones, is this practiced by accordion players?
