1987?

I have a question. I thought ZPhiB/Phi Beta Sigma were the only connection with GLOs in the NALFO.
But I heard that in 1987 Delta Sigma Theta introduced stepping to Lambda Theta Nu by inviting them to step on a unity stroll. http://www.lambdathetanu.org/culture/stepping.html

I know in Florida the FIRM Fam is big, but are there any places that this unknown bond is elaborated on? I thought it was interesting and fascinating.
