A partial discography for Showcase shows the styles and production credits to be all over the map, with soul, folk, and even show tunes. Mop Top Mike wrote to me “The S400 series was the 1965 release numbering for Showcase. They switched it to 98xx in 1966; 99xx in 1967.”

The Beech-Nuts (not the Lou Reed group the Beachnuts – even though he did plenty of work for Pickwick) cut their Showcase 45 at Majestic Studios in Manhattan, a studio also used by the Lovin’ Spoonful. I’ve read the Beechnuts record was bootlegged years ago.

There were at least two other Showcase labels, unrelated to the Pickwick one. Davie Gordon writes, “The 2500 series was from Nashville … the label changed its name to Sound Stage 7 and became Monument’s R&B subsidiary. There was another Showcase label using a 10xx series but it has no connection to the others. It’s from the early sixties.”

2500 – Barbara Grindstaff – Have Mercy (Mr. Lonely) / Where the Red Roses Grow
2501 – Delcos – Arabia / Those Three Little Words (Distributed by Monument Records, Nashville)
