You'll see his name misspelt as Gary Mills, but this is British singer Garry Mills, whose Look For A Star (1960), written by Tony Hatch as 'Mark Anthony', was a hit in the US (where, to add to the confusion, it was covered by Buzz Cason using the name Garry Miles).
Single on Big Top, April 1960 YouTube, one of two released by Gadson that year. Also released on Quality in Canada, and on London in UK and Australia. Arranged and conducted by Stan Applebaum. Charted regionally in the USA.
Mel Gadson's entire discography amounts to the two singles on Big Top. Remarkably little is known about him. A reviewer at Amazon has him born in Sarasota, Florida, in 1937, and that's about it.
Sid Tepper and Roy C. Bennett were prolific US songwriters whose partnership lasted from 1945 until 1970. They wrote numerous songs for Elvis Presley films, and for British pop star Cliff Richard. See their composition I'll Step Down, recorded in Australia by Judy Stone.
