The line-up presents the style of the Cuban sonero septets although in this case there are three lead vocalists who bring the total to nine musicians. What is special about this group is the apparent ease with which the old musicians play the son and bolero, offering a calm intensity and a quiet passion that is difficult for younger bands to imitate.

Los Jubilados' line-up includes the tres guitar for improvised solos and the Spanish guitar for the rhythm section; double bass, bongos and conga, vocals with hand percussion and trumpet. Current members of Los Jubilados who didn't play with Bebeto and Mario in the Conjunto Cubanero know them both from long nights of serenades and informal parties in the house of one or another of the musicians, very much in the tradition of the original Cuban trova. Several were professional musicians who played, at one time or another with the competition: with Mario Patterson's orchestra, with the legendary Orquesta Chepín-Choven or with the Conjunto de Hilario Wilson, which accompanied Celia Cruz when she visited Santiago. Others were talented part-timers - a carpenter, a chauffer a slaughter - house worker.
