Locomotive Breath has problems

I've been having troubles with Locomotive Breath by Jethro Tull. The versions on "The Best Of" and "Aqualung" both start to buzz at 3:23 to the end.

I've reported the problem to iTS and they've given me several song credits to download it again and again. Still bad, even in the iTS+ version. Must be a bad master.

Anybody else found a good version?
