[Tango-L] Is tango the only cross-footed dance

[Michael Figart II]

I've heard quite a few times that Argentine Tango is
the only dance where partners may step on same foot at
same time. Is this in fact, actually true??? I know
extremely little about any other forms of dance, but I
know some of you have extensive knowledge. What do you
think?

Thanks,
