Lyric corrections ; bobbing its head up and down with a singular stare

a souvenir ashtray he bought in Porthcawl ( a British seaside resort of general awfulness)

so throw on your glad rags

Then if memory serves me right it's

just open the tin, think of those gifts you might win

and I'm sure it's not puff the hotwater bottle but I can't think what the true phrase is
