This tune has some special memories for me. A few years ago a small group of our Dallas ukulele club were asked to perform at a special recognition dinner for Ebby Halliday, the premier real estate gal in the Dallas area, and one of the major philanthropists for some area charities. Ebby, now 99 years young, is known to be a uke player, and that evening we played for all the guests coming to the event as they entered and exited the hotel lobby, as well as during one element of the recognition ceremony. Tie A Yellow Ribbon is one of her favorite songs.
Ukulele Bartt is a regular on the ukulele festival circuit around the world and also has some instructional material at his web site, http://www.bartt.net/. Here is Bartt showing how he performs this song. It is a good tune for ukuleles including the banjo uke as shown here.
