I have a question on the Popular Selection List, Level 8. Downton Abbey - The Suite has one of the available sources listed as Contemporary Movie & TV Hits, HAL, p. 38. I have a Hal Leonard Book called Downton Abbey: Original Music from the Television Series. Downton Abbey - The Suite, is on p. 3. Can I use that book instead? They are both Hal Leonard, and the measure numbers indicated seem to match the music that I have.
