Colbie Caillat will also appear on episode 4 and perform the song that jumpstarted her career with the international hit "Bubbly" from her debut album Coco. The silky voiced pop songstress is the daughter of Ken Caillat, a renowned producer who worked with legendary band Fleetwood Mac. Colbie will also perform two other songs from the platinum certified Coco, which include "Realise" and "Battle".

Lastly, three-time Grammy-nominated Joan Armatrading will grace Abbey Road. As an inspirational female musician in the mid-1970s, Armatrading's longstanding career is noteworthy not only because she was a pioneer as a solo performer, but also because her songs are timeless. She will perform "Tall In The Saddle" from her 1979 self-titled album, and "Woman In Love" from her latest album Into The Blues.
