Have you been working on here comes the sun for years? I see an old sheet for here comes the sun in expert mode.
i started writing it in 2010, i did some writing on it in 2012, did a bit more writing on it in 2013, then selected it for recording in 2020 and then finished the writing and then recorded it and made the video in late 2020. the total time for all of that was certainly much less than 1 year
