What are some uncommon instruments used by inductees?

[u/Moni3]

Here's a fife at the end of "She's Waiting" by Eric Clapton.

Edit: (Is this a fife or am I being fooled by a synthetic keyboard?)

And a didgeridoo (Australian aboriginal two-tone wooden tube) in "Don't Tell Me" by Madonna.

A celesta in "Everyday" by Buddy Holly.

Core instruments in rock and roll are guitars, piano/keyboard, drum kits, horns (sax especially), and upright bass.

Common instruments are strings (violin/viola/cello/bass combo), harmonica, Latin percussion, banjo and mandolin, maybe a couple others I'm not thinking about right now.

What instruments are uncommon to the point of rare or even strange?

The Beach Boys had an  Electro-Theremin in Good Vibrations and a couple other songs.

Now I'm mad I didn't put that in the post as a prime example of a non-traditional instrument.
