polka(dot) pronunciation?

[Douglas G. Wilson]

A quick glance at some dictionaries (OED, Cambridge, AHD, RH, Macquarie, 4
M-W's) indicates that British and Australian pronunciation tends to keep
the /l/, while it is optional in the US. Of these, only the M-W 9th
Collegiate goes so far as to show "polka" only with /l/, "polka dot" only
without. My own perception/experience is that both are pronounced both ways
but that the /l/ is much more often pronounced in "polka" (dance) than in
"polka dot".
