In reply to DOSSOME.

@DOSSOME "Waterfalls" was released on at least 3 different compilation albums in Japan since 2003. It only now features a rerecorded vocal because TLC has proved to have a sustainable audience overseas and TPTB feel that the group needs a 3rd person. The re-recording is only a test. TLC attempted this with "R U That Girl?" in the U.S., but people didn't buy into the idea and the show didn't follow through on what it promised the girl who won the right to become Lisa's replacement. It appears you were "ignorant" of this information before you posted. Do your homework next time.
