The Collegiate Shag ... originated
in the South (possibly New Orleans) and has been known at
times as the "Flea Hop" (not just the variation.)
The Shag was popular in the late 1920's and supposedly predates
the Lindy Hop with the
collage students. It was primarily danced to fast Ragtime - Jazz
type music. There were many Intercollegiate Dance Contests held
in NYC in the 1920s-1930's which held a "Shag Division, Conklin
and Coleman won this type of division. Virginia Beach was
a hot spot for the shag as some eastern cities banned the dance.
It was somewhat popular today with some Retro-Swing
dancers in Southern California and is very cool looking with its
Slow-Slow-Quick-Quick rhythm with fast hops and kicks and close contact to your partner is a blast to do.
Over the years this Shag has
split a few times into the various forms. The Collegiate and Murray
Shag can be mixed with basic swing patterns and the
Jig Trot and thus becomes a type of "Swing Bal." (See
Balboa.) The Carolina
Shag was an offshoot of the Collegiate Shag and Charleston
in the 1930s and is more of a Swing dance form than a Shag dance
form today. The Saint Louis Shag is more of a speed dominated/ competition shag, which is different
than the Collegiate, Carolina and Murray Shags. The Balboa (8 count)
was a more subdued smoother variation of the Collegiate shag (6
count), which still shares some similarities today.
Note: A interesting thing in Arthur Murray's 1937 Let's Dance book breaks it down as a Hop-Hop-123 (kicking on 3) but breaks it down differently in his video. The Movie Swing, Swing, Swing has a good musical short of this dance.
