Here is a photo of Francisco Canaro with his orchestra and iconic singer Roberto Maida. This combination is responsible for arguably some of the best tango dance songs out there, right from the heart of the Golden Age of tango, although some stubborn folks may tell you otherwise.
Readers are welcome to help identify musicians on this picture. The smiling man with a dark suit near the microphone is Roberto Maida, and the un-Argentinely tall, next person to the right is Minotto di Cicco, a bandoneonist who once led his own orchestra (song example) but later joined Canaro. The maestro Francisco himself is the second person from the left of the microphone, with a bow tie.
