I'd agree with the view that they didn't have to offer it to you. However from what you've described they've made the position redundant and then immediately advertised for the same position. This isn't legal within six months.
If you've drawn a line under it then fair enough. I'll let you know if we have any vacancies, touring with my band, although you would have to leave your odd political views at home.
Thanks, that would be a great addition to the CV. I have previous experience of touring with bands but none so prestigious.
