It seems that Susan missed the flight to L.A. and did not tape that song as she was supposed to do, the reason being a health problem.
According to a rep for TMZ, “Susan Boyle has had to cancel her performance on “Dancing with the Stars” as her doctor advised her not to sing due to a severe throat infection. Susan is very upset at letting her fans down. Their continued support means so much to her.”
Therefore, host Tom Bergeron announced that due to Boyle’s health issue, Michael Bolton and Ne-Yo are set to sing on “DWTS”.
