TheSingingMixer: #GreenDay's #GoodRiddance #TimeOfYourLife is a poignant look back and ahead. It's no surprise that it's become a go-to #graduationsong. @MarySaxophone crafted this beautiful #violin #piano #banjo #cover & played a lovely version with her on #saxophone, but she invited folks to #collab, so I had to sing along to this lovely arrangement. #joinmycollab if you want to feel a little wistful & nostalgic, too! #tsm
