Stewie, entering dog canyon brought up the info that it was not in the DT or the Forum.

Entering phillips in search-forum brought up a number of threads about him or containing his songs (a number of them not listed in the Related Links), but not the recent thread 58068 where you posted the El Capitan songs.
I remember that some time ago you warned of this problem with songs that you had posted and I should have checked further. Sorry for the duplication.

It does appear in the Related Links of this thread as you point out (but not in all Phillips threads)- I should have checked them but I assumed (wrongly) that phillips in Forum Search would have brought up all threads on Phillips.

Some single song entries came up. Phillips song "Tolono" is posted in thread 7526 (Wabash Cannonball) but it is in the Forum list brought up with -phillips-.

Did you post or check posting of all of the El Capitan songs? Too bad that these were deleted from his web site. It does make the point that no website can be depended on to last.
