heh... in 15 years or so I"ll be considered a senior, so in about a decade and a half, you sould play 70's-2000's hits!
Gives me a chuckle thinking about arranger players gigging at seniors homes to Queen, Nirvana, Michael Jackson, Bon Jovi...
In all seriousness though, whether *25 years ago* or today, when I get requests, they tend to *still* be Sinatra, Berlin, Presley, Righteous Brothers, Platters, Beatles.
Songs like New York New York, Fly me to the Moon, Unchained Melody, Memory, Let it Be, Blue Skies, Always on my Mind, Fools Rush In, Love me Tender, Autumn Leaves, It's now or Never, Over the Rainbow, Smoke Gets in Your Eyes, The Way You Look tonight, Stand By Me, Cheek to Cheek, White CHristmas, Baby it's Cold Outisde, That's Amore, Johnny B Goode, Great Balls of Fire, The Sound of Silence, Georgia on My Mind, Lady, The Gambler.
The request list hasn't changed in 3 decades for me.
