Can it really be 22 years since "Breakout"? http://uk.youtube.com/watch?v=yXL9AkXzlt8
Swing Out Sister made some of the most sophisticated pop music of the mid to late 80s. I always thought that lead singer Corinne Drewery was one of the coolest frontwomen of that decade, with that very iconic short bob hairdo!
They were no one-hit wonders, and I continued to follow their career from "Surrender" http://uk.youtube.com/watch?v=pS3XOEGwSAE through "Fooled By A Smile" http://uk.youtube.com/watch?v=wAHkoe8X9eQ to "You On My Mind" http://uk.youtube.com/watch?v=aYvcmqSs0-w. You could say their music had strong 60s influences - think classic Burt Bacharach for example - and I always thought it was very underrated.
Swing Out Sister continued - and continue - to the present day, as a duo of Corinne and Andy Connell, and as the old cliche goes, they're 'big in Japan'. They have also released their "Beautiful Mess" album in the UK: find some of their ever-sophisticated tunes at their MySpace (http://www.myspace.com/sos06).
And yes, Corinne still has that hairdo.
