Just listen to anything sung by Steve Winwood, and then try repeating what you think he said, and then later compare that to the lyrics on the CD folder.

I challenge anyone to correctly identify any lyrics he sings from just listening. Go to Mp3.com and listen to his version of "I'm A Man" (when he was with the Spencer Davis Group) or anything off of any of his other albums. Absolutely horrid enunciation and an absolute nightmare if you're in a band trying to do covers of his, armed only with the music but not the lyrics -- but his feel is great! :-)
