"Salvation Song"

This morning I listened to Rod Argent's Red House and noticed a small thing in "Salvation Song."  At ~4:03, one of the synths plays the phrase A Bb C F.  With a different rhythm and in a different key (so that it's C# D E A), this same phrase is in the band Argent's "Be Free."  It appears on organ at ~0:09 and on electric piano at ~2:03.
