Catch up with these tomatoes

The lyrics: “Friday night is party time, feeling ready looking fine, Viene Diego rumbeando with the magic in his eyes, Checking every girl in sight, grooving like he does the mambo.”

The song: “The Ketchup Song (Hey Hah),” a Spanish ditty about a fashion-conscious gypsy named Diego who makes up his own brand of rap. Lyrics are a Spanglish version of the Sugar Hill Gang’s 1979 classic “Rapper’s Delight.”

Where it’s charting: Hailed as the successor to the Macarena, the tune, with accompanying dance moves, is No. 1 in 15 countries across Europe -- not to mention Australia.

The artists: Sisters Lola, Pilar and Lucia Munoz, who formed Las Ketchup a year ago. The name honors their dad, flamenco guitarist El Tomate.

The back story: The song got nonstop play in Spain this summer, and tourists wanted to hear the catchy cut when they got home. Pushing Eminem off the top of the European singles chart, the tune has sold 2.6 million copies worldwide.

Cutting the mustard in the U.S.: The sisters Munoz just visited Miami and New York to promote the album (“Hijas del Tomate” or “Daughters of Tomate”). During its fourth week of release, ending Oct. 13, they topped Billboard’s “Heatseekers” new artists’ chart. The single from Columbia Records (not yet on sale in this country) is No. 48 in terms of airplay and, locally, is among the top 10 most requested cuts on KIIS-FM (102.7). The Ketchup video debuts Friday on MTV.
