Artifact: Vintage Tape Reel and Box Noting Paul McCartney Playing Tambourine on the Escorts' 'Night Time'

Via Omega Auctions:

A boxed reel of audio tape (1/4" on a 10.5" reel) with handwritten info to reverse of box stating reel includes recordings by The Escorts - Head to Toe / Night Time inc Paul McCartney on Tambourine.

News reports at the time indicated that Paul produced these two tracks for the Escorts. However, that was later walked back to him helping at the session and shaking some tambourine on the B-side. It's unclear what Paul contributed to "Head to Toe." Maybe handclaps?
