Great question and good choice to post it under this topic.
Wow...I also cannot find any info on this song on the web. Hadn't thought to look when the album was announced!
The only reference very similar to the song title is on Kim Campbell's blog from last year when she wrote:
I find myself recalling the words of our good friend Roger Miller:
'Am I all alone? Or is it just me?'
From: http://www.careliving.org/kim-glen-34th ... niversary/
So you nailed it: the title is typical of Roger Miller's cleverness.
The Second Disc website describes this song in a recent announcement about ADIOS (the bold font is mine):
Roger Miller’s “Am I All Alone (Or Is It Only Me) features a home recording of Miller himself performing the song before seguing into Campbell’s version, on which Glen is joined by Vince Gill on harmony.
Could it be possible that this Roger Miller song has never been released?
Or was it released but under a different title?
Perhaps one of the discographers here on the board knows how to search copyright/publishing databases by song title?
