drinking song symbols

[karl]

 As an idea a saw somewhere, I made a little wineglass symbol
 where in the song you are to take a drink, as in bar 14 in:

 source code in

Perhaps someone would be interested in improving the design, currently 
it is a simple postscript markup:

kippis = \markup {
  \postscript "
0 0.5 moveto
2 0.5 lineto
stroke

1   0.5 moveto
1   1.5 lineto
0.3 3   lineto
1.7 3   lineto
1   1.5 lineto
stroke
"
}
