Theme from S-Express

The song samples liberally from many other works, including heavy usage of Rose Royce's "Is It Love You're After", and TZ's "I Got the Hots for You", which provided the song's campy hook.^[2] The song used the line "Drop that ghetto blaster" prominently from the song "Tales of Taboo" by Karen Finley. The hi-hat is sampled from an aerosol spray.^{[citation needed]} The track's "S express" refrain makes reference to the 42nd Street Shuttle, a line on the New York City Subway. The train sample used is of an InterCity 125. The cover artwork features a cutaway drawing of a British Rail Class 56, a contemporary freight locomotive. For the North American release, some spoken word samples had to be removed due to licensing issues, and were recreated by unnamed voice artists.^{[citation needed]} The female vocalist is Michel'le.^[3]

Ben Thompson from NME wrote, "A mad disco travelogue hosted by a spaced-out Michael Rodd, this is probably in the top five already. The cinematic horny bit from Shaft (I think), lots of train noises. 'Uno Dos Tres Quatros' and they're off. All stations to Dartford via Woolwich Arsenal and Slade Green and No Messing; a synthesiser thump catchy enough to be 'AE IOU' by Freeeze says this one cannot fail. If you were down and out and had only one leg this record wouldn't buy you a cup of tea, but I suppose that's not a factor in this day and age."^[5] Nancy Culp from Record Mirror named "Theme from S-Express" Single of the Week, adding, "Coming on all Seventies and Cerrone (who could forget 'Supernature'?) Mark Moore's S'Express follows on in fine Rhythm King tradition (can the label do no wrong, I ask myself?). You see, the reason these DJs are making such great dancefloor records is that they know what gets you in the groove, man! With this one, you can have a giggle while you dance, too! It has just the right amount of tack/trendy quota to make sure it follows 'Beat Dis' straight to the top."^[6] The magazine's James Hamilton wrote in his dance column, "London DJ Mark Moore leads the Seventies flares fashion with a Rose Royce/BT Express-type buzzing bass synth and hissing hi-hat drive 117-0bpm semi-instrumental, full of samples, quotes and sound effects in current Eighties style, a likely hit."^[7]

In 1999, Spex included "Theme from S-Express" in their "The Best Singles of the Century" list.^[8] In 2020, The Guardian ranked the song number 51 in their list of "The 100 greatest UK No 1s",^[9] writing, "To watch Top of the Pops as 1987 gives way to 1988 is to watch the freaks taking over the asylum: after MARRS and Bomb the Bass's earlier acid house hits, S-Express's sample-heavy track affirmed the sound's chart coronation, making the Stock Aitken Waterman stable look even more square, and stuck one in the eye of London's throttlingly cool club scene with its euphoric, queer collage."^[9] In 2024, Classic Pop ranked "Theme from S-Express" number one in their list of "Top 20 80s House Hits".^[10]
