I'm pleased that you were able to find you father's composition in the Frontera Collection. The archive has a total of eight recordings credited to Manuel Moran. (Click on the link to see them.) Most of them are on the San Jose-Based Fama label, and mostly recorded by Ritmo 7.
Let me know if there is anything I can help you with. Perhaps you can share a bit of your father's career.

This is awesome. Someone, please send me a note, I'm tracking down all my father's music.
