In reality, neither A Special Blend nor Alliance complied with Blackmon's "Rule of Four." However, she granted an exception for A Special Blend, since they were technically a quartet that Warren accompanied at the piano. Alliance, on the other hand, was in clear violation, but Warren, along with Mark Kibble and Claude V. McKnight, III, continued to perform with Alliance stealthily. Although Kibble and McKnight also sang with The Aeolians, they each did so for only one year or less. Warren remained a member of The Aeolians throughout his four-year matriculation.
