Why do people like Rod Stewart?

I don't know, they must be deaf. He has a voice like a  chainsaw hitting a rusty nail.

I'm so sorry you asked this question. I saw it an hour ago and "You're in my heart" has been pounding around in my noodle ever since.

I'm not a big Rod Stewart fan but he's not bad. I can think of lots worse who seem to do very well.

Personally, I grew up in the era before rock n roll so my preferences are for tuneful rather than noisy.
