NASHVILLE, Tenn. (AP) -- Hold On -- Stop using my song.

That's the message to Democratic presidential candidate Barack Obama from soul singer Sam Moore of Sam & Dave fame.

The singer said Saturday that he's sent a letter to the Obama campaign asking them to stop using one of the duo's signature songs, "Hold On, I'm Comin'," at campaign rallies.

Moore says he's not endorsing Obama or anybody else at this time for president.

Obama spokesman Tommy Vietor said in a brief e-mail Saturday that the campaign received the letter and will stop using the song.
