"Calcutta" is a German pop song. An instrumental version by American bandleader and TV host Lawrence Welk on the 1961 Dot Records album Calcutta! was a chart hit, the most successful of Welk's career, and the only tango-based recording to hit No. 1 on the Billboard Hot 100 singles chart. Welk's recording of the tune was something of a departure for him. It incorporated his recognizable "trademarks," i.e., the harpsichord lead and an accordion but combined them with handclaps and a brisk rock rhythm.
