In April and May, Pyrotek Special Effects Inc. was left out of coverage for contributions to the Justin Timberlake and Christina Aguilera tours.

The caption in “Back To Basics” (LD, May 2007, p. 35) should note that the scenic elements were built by Show FX and repaired and augmented by All Access Staging and Productions.
