I'm particularly interested in the tavern or bar scene where they sing "To Life, To Life, Lechaim." Soon, a Russian starts dancing, and he eventually invites Tevye to dance with him. Of course, the tension that existed between the Jews and the Russians was shown during the next few moments. Then, Tevye seems to show his willingness to accept their presence in faith that they would be treated well. Is there any other meaning behind this dance between two nations?
