Were they not on one of the Pebbles/Nuggets albums as an earlier incarnation? I've got a feeling they were involved making "I can only give you everything" (the excellent riff being famously lifted by Beck)or some other garage classic.
I could be wrong, as I often am, but someone here is sure to know.
Moving Sidewalks are on one of the early Pebbles. 99th Floor probably. Vinyl is in the loft so can't easily check which volume.
