Bonnie Rate (spelling) was 40 or very near it, when she got famous. Also.. uh, "If it makes you happy, it can't be that bad," Name escaping me right now.. was well into her 30s.
but we are not living in that type of music industry anymore.. That is why you see major record companies only pushing kids.. Like Justin Bieber, and Taylor Swift and whatever..
meh, I don't want to get into it
Peace
