polish music band 1 2 3???

hello I was in Krakow in Aug and went to a cool little wine bar that was playing some polish jazz/folk music. i asked the bar amid who it was and i think she said it was called '1 2 3' or maybe its 'one two three'. I went to the big music store in the city which she said would have it but it was a holiday and was shut. does anyone know who the band is i am talking about?!?!? or have i forgotten the name
