If I had to guess I'd say Bob's song is set to the Rambling Rover by Andy Stewart.

My list would include

1 bodhrán (Albert Alphonso)
1 student set of tabla
1 much better dahina (treble drum of tabla) pitched to "D" bought from my guruji
2 kanjiras
1 pandeiro
a couple jaw harps (Is Jew's Harp considered an ethnic slur?)
a few sets of bones, both wood and bone
A couple of tongue drums
2 triangles
various bells and shakers
1 darbukka
a few nondiscript frame drums
1 berimbau
3 washboards; 2 metal, one glass
1 udu
1 small gong
1 Earth Drum (paper drum made from recycled blue jeans)
1 set of high hat cymbals
1 Ice Bell (small high sustain cymbal)
1 vibra slap
1 thunder tube (spring drum)
1 flex-a-tone

and still no "real instruments"
