Didn't Rick Astley only ever do like 1 song? 
he had around 13 to 14 club hits - i had all the maxi versions on vinyl at that time - i have all of those in MP3 form now - i actually like Rick and most stuff that was Stock, Aitken and Waterman produced
i would not mind seeing Rick and Imagination or Howard Jones and Go West - the others are more or less of the type that "wont make too much difference in my life if i dont see them
OR even if i do"
I actually went to the Kool & the gang concert - they were one of my favourite bands from the 80's
