That's an interesting game! I'd say go for the king - all three are great options, but if I had to pick one that might strike a chord (pun intended) with senior ladies, I'd say... Elvis Presley!
There's just something about the King of Rock 'n' Roll that exudes charm and nostalgia. Can you imagine singing along to "Can't Help Falling in Love" or "Love Me Tender"? It's like a warm hug for the heart!
