Industry speculation that Neil Diamond and Barbra Streisand would embark on a co-headlining tour in 2005 appears to be incorrect, according to a Diamond spokesperson.

While no details are finalized, an earlier version of this story reported industry talk was heating up regarding Streisand and Diamond hitting the road. One source told Billboard the guarantee for the tour (the amount the acts receive regardless of tickets sold) was in the range of $3.5 million per show.

Calls to both the Streisand and Diamond camps were not immediately returned. Later, a Diamond spokesperson told Billboard via E-mail that the artist has "other plans" for 2005 beyond a 12-date tour of Australia and New Zealand, which kicks off in early March.

The artists, who collaborated on the 1978 No. 1 hit "You Don't Bring Me Flowers," gave their first public performance together in 24 years in June at a Los Angeles fundraiser for presidential candidate John Kerry.

Diamond last toured in 2001-2002, grossing $80 million, and has been known for pricing his tickets conservatively. Streisand played two turn-of-the-millennium shows, taking in $18.2 million at the MGM Grand Garden Arena in Las Vegas. She also grossed $12.6 million from two sellouts at the Staples Center in September of 2000.

Whether they end up performing together or not, most industry observers believe a Streisand/Diamond tour would be a home run for a well-heeled demographic that ponied up to see such tours as Bette Midler and Simon & Garfunkel in 2004. "Streisand and Diamond is the ultimate 60-year-old show," says one industry executive.
