El Preso Nro 9- Señor abogado- Amor gitano
El si de un adiós- Preguntan mis amigos- Cantinero por favor
Las siete de la tarde- Dime amor que está pasando- Ámame
Mendigo sin destino- Asilo de menores- Pocos años
El socio- El fanfarrón- La reina de las feas
La carcel de zin zin-Cancion para un niño solo
