Check out some beautiful waltzes played on a D accordion from Jude Moreau's
CD "Retourner au Les Vieux Temps". Valse a Tolan is one of my favorites
and, like several of these tunes they don't sound right on a C accordion.
Jimmy Breaux has a good number of tunes on his CD's that he played with a D. Most of the Savoy-Doucet cd's are predominately done with D accordions to suit Ann's voice.
Two of my all time favorites Eddie LeJeune (any album) and Horace Trahan (on the Ossun Blues album) do a bunch of songs in D. Also Geno Delafose does the Opelousas Waltz which is a great and simple waltz in D (the Amede Ardoin Opelousas Waltz, not the Austin Pitre Opelousas Waltz which is a completely different tune).
