EDIT (23 April 2020): Made a Lost Media Wiki forum post quoting this post almost verbatim, in case anyone wants to mount a search effort. Link at https://forums.lostmediawiki.com/thread/4542/songs-jerry-dadap-filipino-composer
Note: Every once in a while, I take breaks from bar review to look at historical documents available in the library where I review. Hundreds of Official Gazettes and legislative deliberations lay untouched and unopened, waiting for a historian to open them. I am sharing here in my blog whatever I find interesting, to pique the curiosity of others who may want to look further.
I wonder who Jerry I. Dadap, Jr. is/was and why he has many unpublished songs. All these songs could be lost media, which I earlier talked about. Not sure if Dadap is the same person as Michael Dadap. They could be since the Tumblr page I found on “Jerry Dadap” has the same information as “Michael Dadap” on WIkipedia. (Please forgive me, I just did a cursory search).
Also note the interesting movie titles by Viva Home Entertainment.
It appears all the registrations were made on February 1986, before the regime change.
