LORELAI: Hey, maybe instead of going to college, you should drop out and I could quit my job and we can form an all-girl band with Lane, you know, like Bananarama.
Bananarama, English pop group, formed in 1980 by Sara Dallin, Siobhan Fahey, and Keren Woodward. Their success on both pop and dance charts saw them listed in the Guinness World Book of Records for achieving the world’s highest number of chart entries by an all-female group. Between 1982 and 2009, they had 30 singles reach the Top 50 of the UK Singles Chart, including “Shy Boy” (1982), “Cruel Summer” (1983), and “Robert de Niro’s Waiting” (1984). They performed on the 1984 charity record, “Do They Know It’s Christmas?”. They had eleven singles reach the top 10 in the US, including their #1 hit, a cover of “Venus”, (1986).
Note that this is yet another reference to Lorelai forming an all-girl band.
