What song goes 'tell me why e why e yaaa"?

Ok, it's an older rock song, it's sung by a guy but I think it's a band, not 100% on that though. I remember this part being kinda, slightly higher pitched until the 'yaaa' part.I don't know any other lyrics, it's so good and it used to be one of my favourite songs and I tried googling and youtubing it, but I can't find it. Help me PLEASE!! I really want to listen to this song
