I heard "Take Good Care of Your Feet" by the Beach Boys in a grocery store once. I thought I was on acid.
I heard seal-kiss from a rose in a Ross the other day. They played cher- do you believe in life after love after that so I was just shocked at how deep their music choices were.
The Beatles - She’s Leaving Home From a building’s PA system, and it was even the mono mix at the alternate speed.
I've heard many 50's & 60's deep tracks on Muzak's 50's & 60's channel. A local restaurant plays that channel. Here's an example: "Suddenly You Love Me" by the Tremeloes. First time I ever heard that song was in that restaurant. Always thought of them as a 2 hit wonder here in the States. The channel is also available on Dish Network ch 933. Muzak has come a long way. Back in the early 70's I predicted that Muzak would eventually play original records once the Baby Boomer generation got older.
Blur - Fool's Day in Wilko, a household goods chain in the UK. Fool's Day is a Record Store Day exclusive non album 7" single.
Muzak version - "Surf's Up" (at a supermarket) Real version - "Nothin' To Hide" by Spirit (at Trader Joe's, where they seem to have some sort of deep cuts radio service playing similar stuff)
I was in a JC Penny and saw the video for Larks' Tongues in Aspic on a tv monitor. I had never seen the video before and thought it was pretty trippy. I could only imagine the impression left on someone unfamiliar with Crimson.
I used to live in downtown Asheville, NC (across the street from the Orange Peel). It is hippieville and living there was like living in the 70's again to me. Between the co-op, the cafes and restaurants, and the record and antique stores just on that street, you couldn't walk down the street without hearing the Dead, and sometimes people would stop and listen for a few seconds and rattle off which tape they thought they were hearing. The week that Jimmy Carl Black died, everyone was playing the Mothers, and that's how I initially got the vast majority of my Mothers tapes. That week was really nice because for one glorious week my beloved free jazz was the music of the city and it turns out the most popular items were the Appleton tape, the Rockpile Toronto tape with all the Rubenisms and the big Charles Ives -- which was a blast to hear played in public -- and Absolutely Free.
I was eating lunch at a Taco Bell last summer. The music being played was all 80's pop hits one after another. In the middle of all that I heard Deep Purple Black Night. Couldn't believe it.
I had a holiday in a Spanish campsite when I was 20, sharing a tent with two friends. The tent next to ours was occupied by a Belgian couple who had a strange habit of playing a porn audio tape in Spanish language almost every night to cover their own "noises". Does a porn audio tape count as "deep cuts"?
In a supermarket several years ago, I heard You Must Be One Of Us by Stoneground (Sal Valentino, lead vocal).
McCartney’s Only Love Remains in a Toys ‘R Us McCartney’s Monkberry Moon Delight in a Portland Pizza place John Lennon’s Remember in a San Francisco hotel bar
I'm going to pretend you're not trying to wind me up and answer this straight with examples. The Dead "Mason's Children" is a deep cut. "Playing in the Band" is not. Jefferson Airplane "Watch Her Ride" is a deep cut. "White Rabbit" is not. The Velvet Underground "The Murder Mystery" is a deep cut. "Pale Blue Eyes" is not. Bloodrock "Don't Eat the Children" is a deep cut. "DOA" is not. See how it works? "Obscure" doesn't quite cut it because if you're not old enough to actually have been there (my examples are 50 years old) they all might be obscure to you.
World Market used to have an amazing playlist. I've heard The Pogues "Tuesday Morning" and XTC's "Beating of Hearts" in the store over the years.
A couple of years ago Walmart Radio played ' Sympathy for the Devil' as heard in my local Walmart store number 666.
Once back in the late 70s, I heard 'You Don't Know' by the Thirteenth Floor Elevators in a grocery store! .. well, I was in Houston, Texas at the time ..
