Eric -- according to the Wikipedia (so take this with a grain of salt =D) Pippin opened at Her Majesty's Theatre on October 30, 1973 and ran for 85 performances.
A Chorus Line in London had a fairly successful run. I don't know if it turned a profit, but it ran from July 22, 1976 through March 31, 1979. And fun fact -- Petra Siniawski, the London Cassie, is the only Cassie ever (well, in a Bennett production anyway =)) who didn't wear a red costume -- she wore a blue leotard onstage.
