I believe it is a tubular xylophone, or a close relative thereof.

@Petter That sounds logical.

@pixiedust Must be from years of designing complex relay operated logic control circuitry.

Did you know that the vast majority were not filmed in Italy (Spaghetti land) but in Spain, mostly about 45 minutes drive from where I live. Often, in these movies, I recognise the area. Many of the extras in the film were played by local people I knew.
(I use the past tense as many have since died or moved away.) Famous films like Lawrence of Arabia and the Guns of Navarone were also shot on location here.

@Petter Oh yes..I know the history intimately...always interested in this stuff...think I am a cowboy! ??

I really happy it revived such memories.

What a great story!

@pixiedust It was really cool. Since they were facing us we got the full power of this huge band.

@Sticks48 Some memories can brighten a cloudy day, can't they?

@pixiedust They certainly can. ☺

I much prefer this to the "celebrity" noise and microphone gargling, so much of which passes for music these days.

@Petter Absolutely. Today's music and musicians appear to be manufactured. They just come off a conveyer belt.

Isn't it?
