I'd have happily got half naked on stage even 10 years ago...

[used to do it in my early 20s - well it was hot in summer,
we were that kind of attitude rock band, and girls / some boys in the audience seemed to like it..]

but not any more.. postman delivered my brand new XL+ size belt this morning...😬

We don't all age as discracefully as Iggy Pop... 😜
