This orthographically challenged band poses something of a mystery. The song is credited to George Morton, the famed producer of the Shangri-las (and the New York Dolls–he produced Too Much Too Soon and wrote the song Great Big Kiss), but no one knows who the Beattle-ettes actually were. It is assumed that the extra t in their name is a mistake, though maybe it was some savvy copyright policing.
As it were, the record quotes liberally from the Beatles hits, though notably not My Sweet Lord. Maybe some Shangri-las sang on this or not, it really doesn’t matter. It’s a naked grab for cash, and still kind of catchy and sweet. And I had no idea it existed until yesterday (no quotes from that either).
