As ABBA's success grew, so did the musical ambition of the group's songwriters, Bjorn Ulvaeus and Benny Andersson. One of the first examples of this increased ambition appeared on the second side of The Album in the form of "The Girl With the Golden Hair: 3 Scenes From a Mini-Musical," a triptych of songs written especially for the group's live show. These songs had a pronounced show tune feel that pointed the way toward Ulvaeus and Andersson's future as composers of musicals like Chess. The most popular tune from this "mini-musical" was "Thank You for the Music," an old-fashioned ballad whose appeal extended well beyond the average pop audience thanks to a timeless melody. Like many rock songs, its lyrics pay tribute to the life-affirming qualities of music. However, the tune that supports it harkens back to pre-rock pop: after a jazzy intro, the song gives way to a grandiose melody highlighted by a singalong refrain that lends itself perfectly to being sung by a chorus. ABBA's recording takes the Broadway-friendly feel even further thanks to some flowery keyboard work from Andersson, a dramatic vocal from Agnetha Faltskog, and the huge choral vocal overdubs applied to the song's refrain. The result is a song that whose friendly-to-all-ages appeal makes it perfect for a stage production. This promise was realized when Ulvaeus and Andersson revamped several ABBA songs to create the score for their hit musical Mamma Mia! "Thank You for the Music" is a highlight of that show's score, proving that this duo's Broadway instincts were on target from the beginning.
