This thread is basically a revival of the "Favourite Singers for Specific Pitches" thread, except this time you'd mention songs with your favourite executions of certain notes. A link to the song, and more specifically that part of the song, would always be appreciated.
You can obviously have multiple songs for the same pitch, and multiple pitches from the same song.
C2: Richard Sterban - Elvira - youtu.be/nGKatCAQed0?t=2m10s - he must've done this bass-line thousands of times over the years (from 1981 to the present day), AFAIK he usually goes for the C2 like the original but on at least one occasion he's sung D2 (the Homefree collab), B1 (in the later years mainly I think), and A1 (in an interview) for that particular note. B♭1: Richard Sterban - You're The One In A Million - youtu.be/bw2l7kE8Q-U?t=1m39s - I believe he has executed the same note/pitch live many times as well. B1: Johnny Cash - I Walk The Line (later version) - youtu.be/xAC0vuL3A3c?t=2m32s - B1 in this version and sounded much better than the C2 in his original version IMO. He did go for the low note live sometimes but I think a lot of the time he sort of dodged it by singing higher on the last verse. A1: Junior Brown - Highway Patrol - youtu.be/x_wLVCLPx0M?t=2m18s - a nice and somewhat unexpected note at the end, which is somewhat similar to Paul Brandt's version of the song.
Sorry I didn't post any high stuff, but I'm sure everyone else will be doing that, which might balance things out!
