Lindsey's Arranging On Tango In Night

[Royfan]

Another musician's question - Lindsey is credited as arranger in TITN.

But he's not listed as playing any keyboards - so on EVERYWHERE for example..
I wonder if he came up with those parts, and sequencer parts - and then
Stevie played them?

I don't think those parts were transferred over from guitar.

Anyone have a theory if that song was all his arrangement? (other than
the main chords and melody obviously :-)
