Anna-Bella Munter and Gunnel Sandgren (Bella and Me) were two Swedish 17-year-old girls who left their native country for the UK to work as au pairs. Shortly they were recording a single (their first and the only one) with Columbia, only released in England: Whatever Happened To The 7-Day Week / Help Me Break This Habit (DB 8243, 1967). It was the summer of 1967. After that, one of the girls went back to Sweden, and this was the end for Bella and Me. Fortunately, we have this footage of the pair performing the song on German TV’s Beat Club.
