The search index hasn't been updated beyond (I think) 2005; a big system failure required resources to be deployed elsewhere. Usually the best way to find a thread on a song is to put part or all of the title in the Filter Box and set the Age to all; apart from anything it's faster than searching.

As to why the song wasn't added, perhaps noone (from the DT) found it; I didn't find the title using filter on either Fiddler or Reply ( or Mabus for that matter). If it was buried in a thread without adding a Lyr Add prefix it may not have been noticed.

I was going to look through your posts as the alternative, but 4000 put me off (I scanned about a 1000 and gave up), glad you persevered!
