There’s a news report that: On his last night out, before the oath, President-elect Rodrigo Duterte stepped out at about midnight and went to his favorite hangout, the After Dark Piano Bar, and sang this song…and so I embedded a version of this because it’s not in the Malacañang inaugural playlist…

“DAVAO CITY – Before the burden of an entire nation fell on his shoulders, Rodrigo Duterte enjoyed a final night out yesterday, the eve of his inaugural as the 16th president of the Philippines.
“At about 3 a.m. yesterday, Duterte took the mini stage of the After Dark Piano Bar, his favorite hangout in this city, and sang George Canseco’s “Ikaw.”
“Duterte’s favorite pianist Ponching Fernandez told The STAR that the incoming president even changed the lyrics of “Ikaw” to “kayo” at the start of the song.
“ “He only chose to sing ‘Ikaw’ and after that he left in a little while,” Fernandez added.
“Duterte reportedly arrived at the bar around midnight and stayed until 3:30 a.m. He spent his time with his former dorm-mates at the YMCA Dormitory in Manila.
“He ate his favorite comfort food – fried banana, fried chicken and some pica-pica (bar chow), washed down with a can of Coke Zero.
“Before going to the bar, Duterte spent the whole afternoon of Tuesday rehearsing his inaugural speech.
“Duterte, who is used to giving extemporaneous speeches, practiced delivering his inaugural speech at the Malacañang of the South in Barangay Panacan.” (from the Philippine Star)

Ikaw (You), music by Louie Ocampo, lyrics by George Canseco, performed originally by Sharon Cuneta; here is a cover by Martin Nievera and Sarah Geronimo:
