lyrics vertical movement - help requested.

[Bill Mooney]

Greetings All,
I have been trying to adjust the vertical position of lyrics in a simple 
song.
The default position places the lyrics just a little too close to 
descending stems, in my opnion.
I want to move the lyrics down about half their height.
Hopefully, the attached .ly file with its embedded comments, will show 
what I have done.
Is there a better, more concise, and obvious way of moving lyrics up or 
down while retaining the ability of LP to adjust the positions of staves 
etc., to compensate for those adjustments? (Using lyrictextoffset 
doesn't seem to allow this)
...and Yes! I have read the Manuals! :)
Any help, and comments, would be much appreciated.
Regards
Bill
