Some thoughts:
1) No, not a classical string quartet, the Haydn Quartet was an early vocal ensemble that began as the Edison Quartet in the late 19th century. "Take Me Out to the Ball Game" was written in 1905 so this is one of the earliest recordings (and one of the earliest entries on the list). The popularity of this recording (billed under Billy Murray and the Haydn Quartet even though Murray doesn't sing on it) helped to cement this song into the American canon
2) "Moulty" is an odd choice here. Appearing on the Nuggets collection, it's more of an interesting piece of garage rock than a good one, with its tale of resilience chronicling the band's drummers loss of his arm (years before Def Leppard) a bit unusual
3) Love the Isley's take on "Summer Breeze (and really the whole 3+3 album) and thought it would appear higher. I wonder if the Seals & Croft original will be up higher - for years, I viewed it as the downside of 70s light rock, the Isley's version actually made me appreciate the original more (including the sublime guitar on the original)
4) Hey, remember when ShallowGal listened to the Nationals all the time

Do ya still love 'em, SG? I have to say, sadly, I just do not enjoy them. Ah...different strokes
5) Some nice soul/R&B gems here with Otis' "Shake", The Dramatics and "Monkey Time"
6) "Signs" recently came up with the wife in discussion - she heard the Five Man Electric Band's version not realizing that was an original. She had only heard Tesla's take on it - interestingly enough, I was unaware of the Tesla cover which actually hit top 10 in 1990. My comment: why would you cover that silly song? IMO, doesn't belong here and it better not be bumping off the list some other piece of 70s kitschy gold like "Afternoon Delight" or Rhinesone Cowboy"
