In the early 1980s he had two Top 20 hits as part of Globos with Wendy De Waal, and in 1984, he debuted "Bob Downe", who went on to become his best-known character.

[2] Trevorrow first came to prominence in the cabaret duo Globos with Wendy De Waal, and they scored two Australian Top 20 hits with quirky covers of "Tintarella di luna" (1982) and Sonny & Cher's "The Beat Goes On" (1983), both of which were produced by Red Symons.

"Bob Downe" is a cheesy, safari suit wearing lounge singer with dazzling teeth, and host of the fictional regional daytime TV show Good Morning Murwillumbah.

Bob Downe played throughout the 1990s to ever-larger British audiences, with Trevorrow in perpetual commute between London and Sydney, touring nationally in both countries.

With a multitude of UK TV credits under his beige belt, Bob Downe made his twelfth Edinburgh Fringe appearance in 2002.

In 1999 and 2000, Bob Downe again hosted the Mardi Gras Parade, a consistent ratings winner for Network Ten, and also won the Cabaret Artiste of the Year at the Green Room Awards in Melbourne.

He has collaborated several times with the Doug Anthony All Stars (which included McDermott), appearing in their TV series, DAAS Kapital, and their film The Edinburgh Years.
