Glen Campbell's final studio album Adis was recorded in 2012 in Nashville in the middle of Glen's Farewell Tour. Produced by Glen's longtime banjo player and friend Carl Jackson, the album features Glen singing four Jimmy Webb songs. Adios features songs written by Roger Miller, Bob Dylan, Dickey Lee, Jerry Reed, Fred Neil, and includes a duet with Willie Nelson - 'Funny How Time Slips Away' - and special guest Vince Gill on harmony vocals in 'Am I All Alone (Or Is It Only Me)'.
