Late Friday Afternoon At The Manistique Boardwalk

Wait — only three Drifters? From Google:

The members of the Drifters who recorded "Under the Boardwalk" in 1963 included Johnny Moore on lead vocals, Ernie Hayes on piano, Everett Barksdale, Bill Suyker, and Bob Bushnell on guitar, Milt Hinton on bass, Gary Chester on drums, and George Devens on percussion. Teacho Wiltshire arranged the recording.

Perhaps this video is of a re-recording? Those outfits don’t look like 1963. 🤪
