What qualified as a Motown Revue ?

[jsmith]

......... History tells us that ............
Oct 26 1962: The First Motor Town Revue took to the road ...... BUT ....
Attachment 713
Why wasn't this October 1961 tour classed as a Motor Town Review ???
After all, all the acts were Motown artists [[including the backing band) .....
... ..... ..... so why hasn't this since been credited as the 1st Motor Town Revue ??
.... OBVIOUSLY the 1st one to actually be labeled a MTR was the 1962 tour as that was when the 'name' was concocted, but looked at retrospectively this revue also had to qualify.
