Hey, you guys, did you know there are a surprising number of "hey" songs that topped the charts at #1, including "Hey! Baby" by Bruce Channel (1962), "Hey Jude" by The Beatles (1968), "Hey Paula" by Paul & Paula (1963), "Hey There" by Rosemary Clooney (1954), and "(Hey Won't You Play) Another Somebody Done Somebody Wrong Song" by B. J. Thomas (1975)... and we'll give honorable mention to:
"Hey, Leroy, Your Mama's Callin' You" by Jimmy Castor (1966 - just for fun!)
"Hey There Lonely Girl" by Eddie Holman (1969 - in tribute to that high note that only Eddie could reach)
"Get Off Of My Cloud" by The Rolling Stones (1965 - where would the song title be without "Hey you"?)
"Hey, Good Lookin'" by Hank Williams & His Drifting Cowboys (1951 - "whatcha got cookin'?" - the iconic country song), and
"(Theme From) The Monkees" by The Monkees (more recognizable as: "Hey, hey, we're the Monkees!")
