Given the following context:

Many outtakes from the album have been released or exist. "Time" and a cover version of Dion and the Belmonts' "Teenager in Love" were released on the "By the Way" single. "Body of Water," "Out of Range," "Someone" and "Rivers of Avalon" were all released on "The Zephyr Song" single. "Slowly Deeply," which was featured on the "Universally Speaking" single, is an outtake from the Californication sessions. "Fortune Faded," a song originally recorded during the album sessions was later re-recorded in 2003 and released as a single along with the b-side, "Eskimo," another By the Way outtake. A cover version of the Ramones' "Havana Affair" was also recorded and later released in 2003 on 'We're A Happy Family: A Tribute to The Ramones. The single for "Can't Stop" also features an alternate mix of the song with higher harmonies and a clearer bass line. In 2003, the band re-entered the studio to work on its Greatest Hits album. The sessions produced enough songs for a new album, many which have gone unreleased. Of the songs released, "Bicycle Song" and "Runaway" were released in 2006 as bonus tracks on the iTunes release of By the Way.
In August 2014, unreleased tracks from the album's recording sessions were leaked to the internet. Many of the album's released songs and outtakes are in their earliest forms and feature improvised lyrics by Kiedis. The leak included three songs never heard before including "Goldmine," "Fall Water" and "Rock & Roll" along with the original version of "Fortune Faded." Many of the songs are featured under their working titles (which prior to release were also mentioned in various interviews): Soul Train ("By the Way"), Coltraine ("The Zephyr Song"), I Would Die ("I Could Die For You"), Drone ("This is the Place"), Throw Away ("Throw Away Your Television"), Epic ("Venice Queen") and New Wave ("Quixoticelixer") To date, "Strumming on  D and J", a song assumed to be an instrumental jam and that Frusciante mentioned during pre-album release interviews, has never been released.

answer the following question:

What was the name of the instrumental song never released on the album that featured "Can't Stop"? 

Strumming on  D and J
