Rainbow - since you've been gone. Hello. I usually spend free time to listening pop music. And I sometimes feel strange in some lyrics.. The title is the one.. Fallowing what I've learned at high school, I can't use past present form but specific 'past time' after the word 'since'. But this song's title is "since you've been gone. It's strange to me.. And 'have been gone' is a passive form of 'have gone'? Is it possible? It's totally confussing. Oh.. There are also many contents that write this song's title as 'since you been gone'. I think it's not grammatically strange But I guess this is not correct title. I heard this song many times and i cheched the vocal certainly sounds [you've]. Am I wrong? Is there something i don't know or I got wrong knowledge?
