Dance couple name

Some dance couples put the man's name first other the woman's name.

For convenience of the reader in listings this may be harmonized.

tango.info uses "Adam y Eva", i.e. men first

some naming order possibilities

• men first
• lady first
• alphabetic (Adam y Eva but Eva y Moses)
• the way they promote themselves

for listings

• list them twice
• provide different listings, with all the above orders
