Robin Williamson sang his own October Song in 1966 on the Incredible String Band's eponymous first album The Incredible String Band.
Tom Gilfellon sang October Song in 1972 on his Trailer album Loving Mad Tom.
Maggie Boyle sang October Song in 1987 on her Run River album Reaching Out.
Brian Peters sang October Song in 1998 on his CD The Beast in the Box. He wrote in his album's notes:
[…] Adieu Sweet Lovely Nancy is one of my favourites from the Copper Family—a well trodden song, but sometimes it's nice to do old stuff you really love. Same goes for October Song; at fourteen I worshipped the Incredible String Band as gods, and spent many sore-fingered hours copying the guitar accompaniment to this beautiful Robin Williamson composition from their first record.
The Rheingans Sisters sang October Song as the title-giving track of their 2013 RootBeat album Glad Gold Hearts. They noted:
Our dad brought this song to us a few years ago. We like its gentle observations about the world, the passing of time and the changing of the seasons.
In this video they perform October Song in December 2014 live at Shakespeares, Sheffield:
Lori Watson sang October Song in October 2017 as the monthly digital single of her Yarrow project. This track was released in 2018 on her CD Yarrow Acoustic Sessions. She noted:
I've loved this song since exploring my dad's record collection (including The Incredible String Band) as a teenager. I spent some time working up a version in Rule of Three with John Somerville and Ali Hutton—it was brilliant, but this isn't it. This version is a bit quieter and more contemplative and has formed part of the backdrop to my experience of the natural surroundings in the Yarrow valley. Nature is all-pervasive in that it effects and embodies the inner workings of our minds, psyches and emotions—Williamson has this nailed.
Isn't autumn just stunningly beautiful though? There's beauty and elegance in decay, as well as in renewal.
Jon Wilks sang October Song on The Grizzly Folk's digital single October Song in October 2018. He noted:
As some of you will know, I occasionally play as part of a band called The Grizzly Folk. It's where I got the name for the blog I used to write. This morning we released a new digital-only single. Some of you may know it.
The Grizzly Folk used to play this song occasionally in Japan (where we formed as a band) and imagine that we were 1960s guitar troubadours. It's one of those songs that has just lingered. It's a beautiful thing, originally by Robin Williamson of The Incredible String Band, should you want to seek out/relive its origins.
