Clay's Appearance on "Late, Late Show with Craig Ferguson"

Clay's appearance on "The Late, Late Show with Craig Ferguson" has been canceled. No reason was given for the cancellation.

The unofficial reason from sources is a conflict of interest with Clay performing last night on Jimmy Kimmel Live:

Ferguson was cancelled when the performance was added to Kimmel. It seems you can appear on competing shows within a short period of time but you cannot perform on the competing shows within a short period of time.

Groban or Buble' did Leno and Letterman within the same window but I think it was at least 3 weeks apart so that may give an indication of the gentlemen's agreement/protocol.
