Going to this "well" once too often
Natalie Cole tried this gimmick 17 years ago with "Unforgettable with Love," mixing her vocals with her father's and it worked. She did the rest of the album with only her own vocals and a great band and the result was enjoyable. Having failed to succeed on the same level during the ensuing years, she is back at it again with another "duet." This time, the result is not so good. If you want to listen to these songs, listen to her father's versions. They are a standard that Natalie can't live up to or recreate.
