LORELAI: And, by the way, I got you out of dinner with the Gilmores tonight. I thought you and Dean might enjoy a little Peaches and Herb time together.
Peaches and Herb, vocal duo created in 1966. Herb Fame (born Herbert Feemster in 1942) is the “Herb”, and seven different women have filled the role of “Peaches”. The most famous ones are the first Peaches, Francina “Peaches” Barker (1947-2005), and the third one, Linda Greene, who appeared on their biggest hits, “Shake Your Groove Thing” (1978) and “Reunited” (1979).
It is the song “Reunited” that Lorelai is referring to, with its line Reunited, and it feels so good. The song went to #1 in the US, and was popular around the world. It is unlikely that Rory is quite as excited about her reunion with Dean as Lorelai seems to want her to be.
