How about looking at the 200 #1 hits?
200?
Googled and found this: "The Beatles actually had 27 songs that made it to the number one spot on the American Charts.... they have a cd out called 1, which is all of the songs that made it to the top spot....."
OTOH, if you're referring to Lennon's #1 hits in his post-Beatles days, I believe he got one #1 hit song that he co-sang with Elton John, and then a solo song from his last album that went to #1 after the news of his death.
Perhaps you were speaking metaphorically, as in "a gazillion #1 hits".
