NEW Yorkers will have a chance to see a Grammy winner tonight.Harmonica master Delbert McClinton, whose album “Nothing Personal” was named Best Contemporary Blues Album Wednesday night, brings his roadhouse blues to B.B. King’s.

McClinton puts on a raucous, rockin’ show, filled with Texas twang and greasy-spoon blues.

How well-known is he?

The Beatles used to open for his band in the early ’60s, and McClinton even showed John Lennon a few pointers on the harmonica.

But contrary to blues mythology, “I didn’t teach him anything,” McClinton said.

B.B. King Blues Club, 243 W. 42nd St., at Eighth Ave. [212] 997-4144. Tickets are $45.
