How long is the full version of Santana's "Evil Ways"?

I just downloaded this song, but I suspect it might be a radio edit. My version is three minutes, fifty-four seconds and fades out during Santana's guitar improvisation. Anyone out there have a longer version or is this it?|||It is exactly 3:57 minutes long on the remastered cd and on my original LP record from 1969. It fades out with organ and Carlos's guitar solo. Be assured that you do have the correct album version. This song is short enought that no single/radio version was ever made.
