Black Ensemble Theater's "One Name Only" musical could include Barbra Streisand in its tribute to acclaimed singers who are recognized by just one name (Aretha, Patti, Beyonce). Barbra, whose tours are as rare as those of another one-name musical genius, Prince, will perform her greatest hits plus new music. The new music is "Release Me," a collection of unreleased and untouched -- except for updated instrumentation on two songs -- recordings by Streisand from the beginning of her career in 1963 to 2011.

Why go: Not only will this be a rare appearance by Babs, it could be her final tour, and early stops have brought surprise guests.

Reconsider: Wait, Mrs. Focker is a singer?
