This is one of those gray market releases probably done in the EU where the copyrights have expired.
Only The Lonely is an interesting album. If you want a good version, get the recent MFSL mono release. It sounds rather good for being MFSL.
The stereo version is where the real trick comes into play. ALL versions except very early stereo pressings have drop outs on side two. If you want a good sounding stereo version, the best bet would be to get the stereo version from the British box set or to get the early 1990's Capitol release which was remixed.
If you get the remix, you'll still run into problems. It's missing the original piano intro and it's missing Frank walking off the stage on the last song.
Hope that helps!
