Dave,
There are loads of great Yamaha styles and guitar sounds available for country music. Some of the best, however, have been created by folks in the UK. The vast majority of the guitars, mandolins, fiddles, etc..., are attached to style files as OTS settings, therefore they are only accessible by loading the style file. Once the style file is loaded, you can then copy the individual instrument to your keyboard's User Voice area, thus making it accessible at the touch of a single button.
Now, back to the Electric Slide and Chony's request. Most of the time I do this song using my PSR-3000s 80s Disco style, second intro, second variation, with a tempo of 110. However, most of my audiences are older folks that love to dance--not youngsters at a wedding. If you have an option, I would take Don Mason's advice, put on an MP3 of the song, and go to the restroom. For some songs, Cha-Cha Slide, Old Time Rock & Roll, YMCA, Electric Slide and a few others that entice young girls to get out on the dancefloor and shake body parts, it has been my experience that the original version is what they want to hear.
Sure glad I don't do weddings anymore!

All the best,
Gary
