I know very little about this 45, other than these Madhatters were a group of high schoolers from Stamford, CT who traveled to New York City to record their only 45 in late February of 1966. They broke up soon after, with most members going to college that fall. I’ve also seen the band’s name given as two words, the Mad Hatters.

The Madhatters’ cool original “Just Won’t Leave” has credits to Sills, Young and Davidson. Copyright registration from April 28, 1966 shows words by John Sills, words and music by David Young and arrangement by John Davidson.

John Davidson was the Madhatters lead guitarist, Jim Cantor played bass, and they had a drummer named Eddie (surname?)

For the flip they do a better than average cover of Mike Hugg’s “Mister You’re a Better Man Than I”.

Released on Mask Records (a Jaysina Production, 143 W. 51st St., NY), with Lady Grace publishing. The only other productions I can attribute to Jaysina Enterprises are two 45s by Tommy Walters on Bardell and an Otis Rush session co-produced with Funtown and sold to Gamble.

A 10″ three-song acetate surfaced that contained the two songs from the single plus a version of “I’m a Man”, produced by Jaysina Enterprises, Inc. I haven’t heard the Madhatters’ version of “I’m a Man” yet.

There’s no connection to the Mad Hatters from Annapolis, Maryland (45s on Ascot and Fontana) or Minnesota (two 45s on Cardinal).
