Look at general at the end — that's your definition, pointing to the Spanish dictator. The wordplay builds the full name piece by piece: Fascist leader gives you F (the first letter of Fascist), then controlled gives you RAN, then Houston gives you CISCO (the folk singer Cisco Houston's first name), and finally rumba master gives you FRANCO — that's the Congolese rumba legend Franco Luambo. String them all together and there's your man.
