These three singers alternated singing the lead and backing parts on Los Van Van tracks.  Some of the more notable tracks that Calvo sang the lead part on during this period are "El Negro Está Cocinando", "Mi Chocolate" and "La Fruta".  Calvo was also the lead singer on "Que le den Candela" and "Sandunguera", two famous Los Van Van tracks from an earlier period.

Calvo's trademark look is a thick black moustache and wide-brimmed white hat.
