Want to watch some baseball players, and a few fans, swinging their hips and dancing like gay men at a '70s disco?
When the Dodgers went to play the Rangers in Texas after the all Star Game, Max Muncy invited the team to his house (he lives around there, or is from there) and they had a party. At the party Freddie Freeman did some kind of dance that his teammates glommed on to and they all said he just has to do it at a game and he said he'd do it if he hit a double at the next game. He did, did the dance move when he got to second base and the team did his dance move back to him. Freddie said that anyone else who gets a double has to do it, too. It's become a thing that happens ever since. They were on the road doing this and when they got back to Dodger Stadium, the fans now do it, too.
The Freddie dance is swinging your hips and swaying your arms above your head. They do it from second base, once to the dugout and then turn and do it to the bullpen. (Swing and sway with Sammy Kaye! Heh!) During the disco days I recall someone saying that straight men don't ever raise their hands above their heads when they dance, only gay men do, and that always seemed pretty accurate to me. Regardless, that's all I could think of when they started doing this! (I did it when I went to a couple games this year!)
Unbeknownst to me, until just an hour ago, the British rock band Freddie and the Dreamers had a single out in 1965 called "Do the Freddie" which was a short-lived dance craze for a couple months. (Freeman's Freddie dance is not quite the same nor was it inspired by this song.) A youtube poster did a montage of Dodgers players doing the Freddie all summer and edited it to this song! Here's the link!
