[Verse]
Kahit na kasama ka, ako'y nangangamba
Kailan ma'y alam kong hindi kita maaangkin
Kay sarap isiping itoy hindi magwawakas
Ngunit 'di natin batid na ang lahat ng itoy hiram
Maliligayang araw, kung ika'y magwawakas
Hanggang kailan, sabihin mo hanggang kailan
Hanggang Kailan was written by Rey Valera.
