Aretha and Condi -- for one night only

R-E-S-P-E-C-T, meet D-I-P-L-O-M-A-C-Y.

Aretha Franklin and Condoleezza Rice will share a stage next month in Philadelphia at a benefit concert for inner city children.

The Queen of Soul and the former secretary of state will headline a July 27 concert at the Mann Center, according to its Web site:

"Ms. Rice will enchant us with selections from Mozart and more and will feature Aretha on vocals with selections from her new album, 'A Woman Falling Out of Love.' This extraordinary effort is sure to be a crowd pleaser."

It should be an especially good night for Rice. She won her first piano competition at age 15 playing Mozart's Piano Concerto in D Minor and told The Post in 2006 that one of her favorite song's is Franklin's "Respect." (She also said she enjoys working out to Cream's "Sunshine of Your Love.")

Tickets for the show range from $24 lawn seats to $95.
