Bob Gelman started the Yahoo Yamaha arranger group WAY back. Actually it was two groups; one for styles, one for songs. I had the honor of doing the first song posted, Honky Tonk. As the new social media and groups such as PSR Tutorial became popular the two groups lost popularity and dwindled down to nearly nothing.
At the time though, it was the place to go to share experiences for Yamaha arrangers.
