It's very easy for people to mock Rick Astley as a SAW product who disappeared into obscurity but he is much more than that. From what I have read, he quit the music business to spend time with his family (he and his girlfriend had just had a baby daughter) but during that time he continued to write music. He wrote songs for various performers and he himself appeared on tracks by MAX and wrote soundtracks for Scandanavian films (not 'that' sort of Scandanavian film though). His German released album 'Keep it turned on' was great and his album of covers really showcased his distinctive voice.
The biggest problem with Rick Astley is we haven't heard much from his fantastic voice in the intervening years. Surely one of Britain's premier singers- puts the XFactor wannabees to shame. Personally I hope this award is a springboard to launch another album of self penned tracks.
