Its biggest promotional work to date will include TV, radio and cinema ads as well as roadshows across the country.
Vimto says it wants to achieve "double-figure" sales growth this year.
The creative features Lucas singing the classic 70s track D.I.S.C.O, but substituting the letters V.I.M.T.O. The ad is designed to make the tune a playground chant and, in doing so, put the brand in the minds of its target audience of five- to 11-year-olds.
Vimto spent just under £1m on advertising last year, according to Nielsen Media Research. However, advertising alone for the latest campaign is being backed with a £1m-plus spend through Cheetham Bell JWT.
The campaign will also continue to feature the Purple Ronnie character, which has been associated with the brand for the past seven years.
Television activity will break nationwide on March 8, with increased coverage in the Granada and Midlands TV regions. The campaign will appear in cinemas at Easter and then again in the summer with ads running alongside films such as the Shrek sequel and third Harry Potter movie.
Creative for the cinema ads differs from the television work, with the screen panning out to reveal the image of a cinema full of children.
Press executions will also feature in a selection of women's titles for the first time. Previously, Vimto had only targeted mothers through TV, but the mixed-media approach is intended to ensure maximum reach.
The promotional assault will also include in-store activity, such as sampling to "educate" mothers about Vimto.
Vimto sold 12 million bottles of cordial, 26 million bottles of carbonate and 92 million cans of drink last year.
