Huzzah, a diner! We have a '50's style diner in my Midwestern US city (about four blocks from where I live), but it doesn't have a jukebox (good burgers and shakes, though). That style of 'railcar diners' goes back a bit further into the early 20th Century, and in many cases was a matter of convenience - many of the early diners were near train stations (so travelers could jump off during a stop and grab a quick lunch if they didn't want to pay for train food), and some of the early pre-fab builders had their roots in railcar building, so using that layout as a starting point made sense. Gradually they got detached from that railway association some and became a bit of a trope. The 'Baxter's' name may be a reference to the Jefferson Airplane album 'After Bathing At Baxter's', which was their first full blown psychedelic album ('Surrealistic Pillow' was their prior release, which had 'Somebody To Love' and 'White Rabbit' on it, but also still had a fair number of songs from their folk background. I was going to say the album on page 7 could be 'Crown of Creation', their next album, but I don't think it is after looking at the cover of that one.)
Vintage jukeboxes are terrible for serious playback. Most of them use comparatively high tracking force (the amount of downforce on the stylus/needle to keep it on the record), and the combination of that and usually not changing the stylus often enough results in the records being worn very heavily, particularly since in the 50's and 60's the operators would be changing out the discs to keep the popular records in the machines so they would get played (and make money a dime at a time). There is a small community of folks who collect, repair, and use them, but no one puts their best 45's in them - you want a copy that you don't mind getting worn out. This particular model looks to be a
Rock-ola 1448. (Hitting the jukebox was a way of dealing with several different faults, including a record that was skipping, and was popularized by the character Fonzie from the 70's throwback sit-com 'Happy Days.')
Home cutting lathes were a stop-gap - most serious recordists moved to reel-to-reel tape by the early '50's, but if you wanted to have something that could be played more widely, a disc was the way to go for many years, so many bands that were trying to break into the business walked out of demo sessions with a few of these to shop around. Unfortunately, because the blanks used to record onto were softer than normal record vinyl, they tended to wear badly (like the X-ray records mentioned along the way a few chapters back). Trying to use one in a jukebox is poetic license, at best, but makes for a nice story. Kind of like trying to use a diamond earring as a cutting stylus, or trying to make your own blanks from scrap plastic.
Rocket 88 was a model of the Oldsmobile 88. (Lots of good rock & roll songs about cars.) The Route 66 similarity is coincidental, though humans do tend to like doubled numbers for some reason.
Thanks very much for the chapter - this series is so much fun, and the end notes are great! Keep up the fantastic work!
