removing tags

[Bernard Hurley]

Hi all,

Is there any way of removing tags from music? For instance naively one
might expect:

=====================
one= {a'' \tag #'A b'' c'' \tag #'C f''}
two = {\keepWithTag #'A \one }
three = { \tag #'B \two \tag #'E a'' }

{
  d'' \keepWithTag #'B \three
}
=======================

to display the same as: {d'' a'' b'' c''}. However:

 \keepWithTag #'B \three

removes the note b'', presumably because it is still tagged with #'A. Is
there any way of removing all the tags from \two?
