Pebbles & Bamm Bamm on KFWB (1965)

Here’s a fun website to browse: Radio Use Only is a new site devoted to collecting and making accessible downloads of rare radio station promo discs. One highlight is this rare Hanna Barbera recording especially made for Los Angeles radio station KFWB, featuring the song (with special lyrics) “Open Up Your Heart and Let The Sunshine In” (famously featured on the 1965 Flintstones episode “No Biz Like Show Biz”).
