[TOMT] I wonder why as time ticks by..

Trying to find this song stuck in my head. its still on the radio once in awhile probably from 90s and it is NOT green day it's a mellow male voice light guitars "I wonder why, as time ticks by, (something something) I..." he's got a very distinct voice probably English with the accent on the Why and By

I'm sure someone out there knows it thanks!
