Frost/Nixon: With timing that could either be viewed as fortuitous or unfortunate, Tampa gets to see Frost/Nixon the play just a few days before we see whether Frost/Nixon the movie (based on the play) wins any Oscars. How will the Richard Nixon of Best Actor nominee Frank Langella compare with that of Stacy Keach, who's playing Nixon in the national tour? One reviewer said that Langella's Nixon is more reptilian, Keach's more gutter. Both actors have a powerful stage presence — it might be a draw. Peter Morgan's script looks at how British TV interviewer David Frost extracted an implied admission of guilt from the former president for his role in the Watergate scandal. Feb. 17-22. 7:30 p.m. Tues.-Fri.; 2 & 8 p.m. Sat.; 2 & 7:30 p.m. Sun. Carol Morsani Hall, Tampa Bay Performing Arts Center, 1010 N. MacInnes Place, Tampa, $35.50-$57.50, 813-229-7827, tbpac.org.

Also on Tuesday:

John Davidson. Wow. John Davidson. My mother used to have a crush on John Davidson. She's very old. I guess John Davidson must be, too, but he still looks kind of cute in a silver-fox kind of way. If you're the kind of person who likes dimply crooners, or your mother is, this is the concert for you. (And it's in the afternoon, so she won't have to stay up too late.) Feb. 17, 1 p.m., Ruth Eckerd Hall, $16-$20, rutheckerdhall.com. Pre-show lunch with John Davidson at 11 a.m., call 727-791-7400 for tickets.
