The search results indicate that the song “Mula Mere Mula” is primarily associated with the singer Roop Kumar Rathod and the movie “Anwar.” While Harshdeep Kaur has sung a song titled “Maula Maula” from the album “Rubaru,” and also a song called “Zaalima” with Arijit Singh, there is no clear indication of her singing the song “Mula Mere Mula” from “Anwar.” The provided lyrics and associated information consistently point to Roop Kumar Rathod as the main vocalist for “Maula Mere Maula” from “Anwar.” Therefore, I cannot provide the authentic chords and lyrics for ‘Mula Mere Mula’ by Harshdeep Kaur as the available information does not support her performing this specific song.
