In his own words, DOC plays ‘a little bit of everything and a whole lot of nothing’ In one set his repertoire may include a be-bop jazz tune, some modern jazz, rock and roll, Latin sambas, original ballads, some pop songs, blues, country and swing. You never know what songs DOC will pick out of his extensive song-list of over a thousand numbers that cover a 70 year period of musical history, but you can be sure that it will be different every night.
