Seagrams VO is a 7 and 7?

No, VO is a different whiskey made by Seagrams. Seagrams VO is one step up from Seargams7. (and I consider Seagrams VO to be one step down from Crown Royal)

Seagram's Seven Crowns is an American blended whiskey. Both VO and and Crown Royal are Canadian.

A "Seven and Seven" is a cocktail made with Seagram's Seven Crowns and 7-Up.
