"So Long" is a jazzy, acoustic blues song featuring Detroit blues legends Buddy Smith and Thornetta Davis. As a part of Drew Schultz's Back To Class project, 50% of the profits benefit the music programs of the Detroit Public Schools.

Buddy Smith is one of the many legends of the United Kingdom’s Northern Soul scene. In the 1960s he was a prolific performer around Detroit, releasing a single called “When You Lose The One You Love.” The song was written by Tony Clarke, who had contributed songs to artists including Etta James and David Ruffin, and arranged by McKinley Jackson, a Detroit staple whose work with Holland/Dozier/Holland, Chairmen of the Board, Freda Payne, and the Invictus/Hot Wax labels would continue to cultivate the "Detroit Sound” even after Motown Records had relocated to California. Buddy could not have guessed that, decades after the single’s release, the song would gain him notoriety among the Northern Soul crowd in England, where an original copy of his single would sell for 1,600 British Pounds. Today Buddy still performs all over Detroit, recently releasing a new album called “Life Ain’t Nothin’ But A Song," and his voice is just as strong as ever.

Thornetta Davis has earned her label as the “Princess of Detroit Blues,” working with artists including Alberta Adams, Bob Seger, and Kid Rock while performing her original material on bills with Etta James, Gladys Knight, and Bonnie Raitt. She has won countless Detroit Music Awards, and her voice has been heard in the HBO drama The Sopranos, the 2001 film Osmosis Jones, Xena Warrior Princess, and the VH1 Vogue Fashion Awards at Madison Square Garden.

“So Long” featuring Buddy and Thornetta continues Drew's Back To Class project, with 50% of profits donated to the music programs of the Detroit Public Schools. Schultz and his band, The Funk Machine, performed in Detroit July 2013 to showcase the project at Don Was' All Star Review for the Concert of Colors, and a private party at Motor City Casino saw the first donation to the Detroit Public Schools Foundation of $1,000. The project was featured in international press including Modern Drummer Magazine, SoulTracks.com, and Big City Rhythm & Blues Magazine, and prompted Susan Whitall of the Detroit News to dub Schultz "Kid Motown."
