I am excited to share the link to the updated and OH-SO-FUN Rightstart songs! They have added the first verse to Yellow is the Sun and there are two versions. One version is sung by a class of children (adorable) and the other one is for jamming out with your kids! My kids loved it! There was smiling and dancing everywhere! Writing the Numbers and the September songs are updated, as well. Sheet music files are there for those who like to make their own music.
Make sure you scroll down the page and look under the picture of the CD under “Files” and click on the links for the sound files. You can also buy the updated CD for $3.00. Hope this helps!!!
