"Did I Let You Know" is a song from the Red Hot Chili Peppers' 2011 album I'm with You and was released in January 2012 as a radio-only single exclusively in Brazil.
On December 13, 2011, the band released a statement on their Brazilian website saying due to the song getting heavy radio airplay in Brazil and the song winning a poll voted on by the fans they decided to make it the next single there.
Through the project “A Mosca Sabe” (The Fly Knows) fans from all over the country were selected to be part of the video.
The devoted fans then got together in the city of Rio de Janeiro to shoot the video.
Thanks so much!” while Klinghoffer responded by saying “I just wanted to say that the smiles on all of those beautiful faces and the love that is very clear throughout that video made me a very, very happy camper.”[3] MTV Brasil aired the video on Monday March 19, 2012 on the show, Acesso MTV and interview those that helped create it.
