"Party Train" is from 1983's Gap Band 5: Jammin', the last of 4 straight gold or platinum albums for the band. While the song peaked at #3 on the R&B charts, it surprisingly did not break the top 100 on the Billboard pop charts. The album peaked at #28, although it did hit #2 on the R&B album charts.
The video is classic Gap Band -- flashy, exuberant and fun. Yes, the Wilsons loved their cowboy hats and boots (they were, after all, from Tulsa). However, the video is just a crazy, funky California beach scene. With the exception of Charlie Wilson's ill-advised (really small) bathing suit, this clip is a winner. And there is even dancing with roller skates (briefly, around 4:37).
Although the Gap Band's popularity declined after the 1980's, they continued to perform until Robert Wilson's untimely death from a heart attack in 2010.
A rarer Gap Band classic, "Burn Rubber on Me (Why You Wanna Hurt Me)" was posted on ERV in January 2014.
