The Roulettes played regularly on local radio station 6PR's Hillbilly Hour. Becoming even more involved in the local scene they started the first rock and roll dance sessions at the Maylands Town Hall, however after working on establishing their band on the local scene, Doug and Leo became ambitious enough to attempt their luck in the east of Australia. Putting their car George, a Ford Anglia, on a ship they departed on a four-day voyage to Adelaide, and after sight seeing that city over three days, they drove the rest of the way to Melbourne.
Over a three-month period in the southern capital they gained work on the local dance hall circuit and also gained some notoriety by appearing on a number of local radio and television shows. At one stage they gained a musical coup of sorts by being asked to back Johnny Rebb on one of his Melbourne shows. Johnny Rebb was one of the top acts at the time. De Kroo had also been entertaining crowds singing live during the intermission between back to back movies starring the new sensation Elvis Presley, by impersonating his sound and moves. At about the same time they met Bob Rogers and John Laws, and de Kroo was informed he sounded like Elvis but John Laws on hearing this said that t hey should follow The Everly Brothers lead and so they became The De Kroo Bros. Arriving in Sydney the brothers not only changed their stage name but in appearance and style fashioned themselves after the American Everly Brothers duo. Their repertoire now included a mixture of rockabilly, country and western and pop harmonies.
After reaching Sydney, The De Kroo Bros also entered the world of all the major television shows at the time simply by telling the producers they were good enough. Accepted at the time by the television studios, The De Kroo Bros soon became known for their playing of live gigs on Bandstand, Australia's Amateur Hour, The Graham Kennedy Show, The Bobby Limb Show, Six O'Clock Rock, Teen Time and the Youth Show. Brian Henderson and Bandstand travelled with The De Kroo Bros in 1965 to Canberra for early versions of today's ubiquitous talent shows, and even to Papua New Guinea for filming and such. De Kroo's association with other well known singers and shows at the time included one with Johnny O'Keefe who as a part of that relationship had The De Kroo Bros provide live performances on the Sing, Sing, Sing which ran from 1962 to 1965. Col Joye was their manager at the time.
There signing with Columbia Records resulted in the release of their debut single "On The Job Too Long" and then six days later another single, "Loveland". Both of these tracks suffered from lack of playing and did not do well. Columbia also released other singles, and whilst two of these did reach the Australian Top 100, Columbia did not take up the option of renewing their one-year contract.
The brothers then signed with Festival Records. In October 1961 The De Kroo Bros played as the support bill for the Cliff Richard and the Shadows Show tour of Australia and New Zealand, and with their new record company successfully reached a top 10 single on the national charts with "(And Her Name Is) Scarlet" (released 1963) which reached hit single status in Australia in 1963, especially in the cities of Sydney (#4), Brisbane (#1), and Perth (#5). "(And Her Name Is) Scarlet", had been written by Herb Newman, although the writer credit on record labels has been to a pseudonym, either Barry Stuart or Steven Howard, and had been released in America by Bob Wilson.
In addition they had four other singles that all made it to the Australian Top 100. By 1965 Leo and Doug were so popular that the Australian Women's Weekly even included a "how-to" article on knitting a mohair Beatles style jacket just like those worn by the De Kroo "top pop boys". In 1987 Canetoad Records released a compilation album. In 1988 Festival Records also released a compilation album. The compilation albums have tracks included that were not part of The De Kroo Bros singles releases.
Other than television and live performances, The De Kroo Bros continued to play the club circuit until an amicable split in 1972. Leo and his wife Marianne then moved from Pymble in Sydney and bought a property at Eumungerie near Dubbo. De Kroo continued to pursue his luthier work but also worked as a weekday morning radio announcer from 1999 to 2008 at 2DU. Doug De Kroo died in 2025.
