Found. A site in good ol' Russia selling Walter Becker's Circus Money online for $1.62!
That amount will buy you the whole record as mp3-files in VBR-quality.
Yes. The say they're legal but the low, low, low prices tell another story. At least that's our take on it without having scrutinized the legal stuff. All we know is that these Russian sites have been hunted for years and just keep on poppin' up under new names.
