Here are my CubeSERV observations:

CubeSERV OGC:WMS 1.1.1 GetLegendGraphic requests:

This is a layer with multiple classes:

http://ceoware2.ccrs.nrcan.gc.ca/cubewerx/cubeserv/cubeserv.cgi?service=
WMS&version=1.1.1&request=GetLegendGraphic&layer=CANADNAODA_L%3ACEOWARE2
&format=image/png

This is a layer with a single class (i.e. all point symbols are the
same)

http://ceoware2.ccrs.nrcan.gc.ca/cubewerx/cubeserv/cubeserv.cgi?version=
1.1.1&service=WMS&request=GetLegendGraphic&layer=GCDB_INDEX:CEOWARE2&for
mat=image/png

The layer title does not show up as part of the image.  This is default
behaviour.

Here is the same layer (single class) with the layer name embedded in
image via 'GetLegend'

http://ceoware2.ccrs.nrcan.gc.ca/cubewerx/cubeserv/cubeserv.cgi?version=
1.1.1&service=WMS&request=GetLegend&layers=GCDB_INDEX:CEOWARE2&format=im
age/png

Here are both layers in a GetLegend:

1.1.1&service=WMS&request=GetLegend&layers=GCDB_INDEX:CEOWARE2,CANADNAOD
