Wow
Garth Hudson was my favorite musician in my favorite Band. I saw them first at the Before the Flood concert with Dylan in LA, then 5 times on the farewell tour, including the closer Thanksgiving Day in SF at The Last Waltz. I like to say that there's 50 concerts in my Top 5 - here's 6 of them!
I was also fortunate enough to see several post-Robbie versions, including the Cate Brothers tour, after adding Jim Weider, and then replacing Richard Manuel with Richard Bell. Not relevant to Garth, but I add here the Helm/Danko acoustic duo concert - another top 5.
Through it all, Garth made 1 band into several. Here's his credits from the Brown Album – organ, clavinet, piano, accordion, melodica, soprano, tenor and baritone saxophones, slide trumpet. Wikipedia also includes bass pedals, but I'm assuming those were part of his Lowrey Festival organ.
There are very, very few concert moments more exciting than when Levon would pick up the mandolin, Richard Manuel shift to drums, and Garth to piano. Though Rick Danko taking Garth's seat at the organ so that he could fiddle and play the bass pedals was an added treat!
